Eye Cancer

Eye cancer can occur in many parts of the eye where a tumor can occur. Because of this there are several types of ocular cancer. Their occurrence varies in the age of the affected individual. This article will focus on retinoblastoma, the most common eye cancer in children, and intraocular melanoma, the most common eye cancer in adults.

Retinoblastoma can occur at any age but is most often seen in children younger than five. About 200 children a year are diagnosed with it in the United States. Retinoblastoma starts with a small tumor in the retina, the very back of the eye. In growing children, the retina originates from cells called retinoblasts that grow and divide very quickly. These cells eventually become the mature cells of the retina when they stop growing. In the case of retinoblastoma the retinoblasts don't stop growing and form a tumor that can continue to grow and cause further complications if not treated quickly.

Retinoblastoma typically has three classifications: intraocular, extraocular and recurrent retinoblastoma. In the intraocular form the cancer can be found in one or both eyes but not in tissue external of the eye. In the extraocular form the cancer has spread outside the eye. It can spread to the tissue surrounding the eye or it can invade other areas of the body. In the recurrent form the cancer returns after already being treated. It may recur in the eye, its surrounding tissues, or elsewhere in the body.

Intraocular melanoma is a rare cancer overall, yet it is the most common eye cancer seen in adults. It is when cancer cells are found in the uvea of the eye. The uvea includes the iris (the colored portion of eye), the ciliary body (an eye muscle that focuses the lens) and the choroid (found in the back of the eye next to the retina).

Intraocular cancer of the iris usually grows slowly and usually doesn't spread. The tumor is seen on the iris as a darker spot than the surrounding area. Intraocular cancer of the choroid or ciliary body occurs in the back of the eye. They are classified by size with a small tumor being 2-3 mm or smaller and a medium or large tumor being bigger than 3 mm.

Intraocular cancer can spread and become extraocular as well. If not found and treated early enough it can spread to the surrounding tissues, the optic nerve or into the eye socket.

Causes and symptoms

Genetics is thought to play a role in eye cancer. In regards to retinoblastoma, it is believed that if a tumorhereditary retinoblastoma have a rare risk of developing a tumor in the brain and should be monitored on a regular basis. develops only in one eye then it isn't hereditary. However, if a tumor occurs in both eyes then it is hereditary. Those who have

The cause of intraocular melanoma is still vague. Genetics could play a role, but age is also a factor. Inter-estingly enough, this type of cancer is seen most often in white people from a northern European descent.

The symptoms of this type of cancer usually begin with blurred vision and tenderness of the eye. Advanced symptoms may include loss of vision. If these symptoms persist a person should make an appointment with their ophthalmologist.

Endometrial Cancer

Endometrial cancer is a type of cancer that begins in the uterus. The uterus is the hollow, pear-shaped pelvic organ in women where fetal development occurs.
Endometrial cancer begins in the layer of cells that form the lining (endometrium) of the uterus. Endometrial cancer is sometimes called uterine cancer. Other types of cancer can form in the uterus, but they are much less common than endometrial cancer.
Endometrial cancer is often detected at an early stage because it frequently produces abnormal vaginal bleeding, which prompts women to see their doctors. If endometrial cancer is discovered early, removing the uterus surgically often eliminates all of the cancer.

Endometrial Cancer Symptoms

Signs and symptoms of endometrial cancer may include:

• Vaginal bleeding after menopause
• Prolonged periods or bleeding between periods
• An abnormal, watery or blood-tinged discharge from your vagina
• Pelvic pain
• Pain during intercourse

When to see a doctor

Make an appointment with your doctor if you experience any signs or symptoms that worry you, such as vaginal bleeding or discharge not related to your periods, pelvic pain, or pain during intercourse.

Causes

Doctors don't know what causes endometrial cancer. What's known is that something occurs to create a genetic mutation within cells in the endometrium — the lining of the uterus. The genetic mutation turns normal, healthy cells into abnormal cells. Healthy cells grow and multiply at a set rate, eventually dying at a set time. Abnormal cells grow and multiply out of control, and they don't die at a set time. The accumulating abnormal cells form a mass (tumor). Cancer cells invade nearby tissues and can separate from an initial tumor to spread elsewhere in the body (metastasize).
 

Brain Tumors

The term "brain tumor" includes any tumor within the skull: tumors that are within the substance of the brain and those that are outside the substance of the brain but within the skull.  In addition, there are tumors that start within the skull and tumors that come from someplace else (like the lung or breast, for example) and metastisize to the brain or the coverings of the brain.
When brain tumors are malignant, they are classified as cancerous. There are 130 different types of brain tumors, making diagnosis and treatment very difficult. More than 612,000 people in the U. S. are living with a diagnosis of a primary brain or central nervous system tumor.
Tumors that start in the brain are called primary brain tumors. Often, tumors found in the brain have started somewhere else in the body and spread to one or more parts of the brain. These are called metastatic brain tumors (or brain metastases). Metastatic brain tumors are more common than primary brain tumors.
The types of cancer that commonly spread to the brain are melanoma and cancer of the breast, colon, lung, and unknown primary site. The types of cancer that commonly spread to the spinal cord are lymphoma and cancer of the lung, breast, and prostate. About half of metastatic brain and spinal cord tumors are caused by lung cancer. Leukemia, lymphoma, breast cancer, and gastrointestinal cancer may spread to the leptomeninges (the two innermost membranes covering the brain and spinal cord).
Brain tumors are the deadliest form of childhood cancer. Brain stem gliomas, atypical teratoid/rhabdoid and glioblastoma multiforme have survival rates of less than 20 percent. Non-malignant/benign brain tumors can kill children if their location in the brain prevents surgical removal or other curative treatments. Pediatric brain tumors aren't like those in adults. Children's brain tumors require specific research and different treatments. Even though survival rates for some childhood brain tumors have increased over the past 30 years, survivors often suffer from lifelong side effects of treatments such as surgery, radiation and chemotherapy.

Removing adult tumors through surgery

If doctors think there may be a brain tumor, a biopsy may be done to remove a sample of tissue. For tumors in the brain, the biopsy is done by removing part of the skull and using a needle to remove the tissue sample. A pathologist views the tissue under a microscope to look for cancer cells. If cancer cells are found, the doctor may remove as much tumor as safely possible during the same surgery. After the surgery, a pathologist checks the cancer cells to find out the type and grade of brain tumor. The grade of the tumor is based on how abnormal the cancer cells look under a microscope and how quickly the tumor is likely to grow and spread. A CT scan or MRI may be used to find out if any cancer cells remain after surgery.
The following tests may be done on the tumor tissue that is removed:

• Immunohistochemistry study: A laboratory test in which a substance such as an antibody, dye, or radioisotope is added to a sample of cancer tissue to test for certain antigens. This type of study is used to tell the difference between different types of cancer.

• Light and electron microscopy: A laboratory test in which cells in a sample of tissue are viewed under regular and high-powered microscopes to look for certain changes in the cells.

• Cytogenetic analysis: A laboratory test in which cells in a sample of tissue are viewed under a microscope to look for certain changes in the chromosomes.

Sometimes a biopsy or surgery cannot be done safely because of where the tumor formed in the brain or spinal cord. These tumors are diagnosed based on the results of imaging tests and other procedures.

Cancer of the Anus

The anus is the body's opening at the lower end of the intestines. The anal canal is the tube that connects the lower part of the large intestine (rectum) to the anus and the outside of the body. As food is digested, it passes from the stomach to the small intestine. It then travels from the small intestine into the large intestine (colon). The colon absorbs water and liquid from the digested food. The waste matter that is left after going through the colon is known as feces or stool. Feces are stored in the rectum, the final 6 inches of the digestive system. From there, they pass out of the body through the anus as a bowel movement.
The anal canal is about an inch and a half long. Its inner lining (called the mucosa) is made up of several different kinds of cells. Learning a little about these cells is helpful in understanding the kinds of cancer that develop in various parts of the anal canal. Glands and ducts (tubes leading from the glands) are found under the mucosa. These glands make mucus, which acts as a lubricating fluid.
The anal canal goes from the rectum to the anal margin (where the canal meets the outside skin at the anus). About midway down the anal canal is the dentate line, which is where most of these anal glands empty into the anus.
Cells above the anal canal (in the rectum) are mainly shaped like tiny columns, while most of those in the upper anal canal just above the dentate line are shaped like cubes and are called transitional cells. This area is called the transitional zone. Below the dentate line are flat (squamous) cells. The anal margin (also called the anal verge) is lined by squamous cells that merge with the skin just outside the anus (called perianal skin). The perianal skin is also made up of squamous cells, but it also contains sweat glands and hair follicles; the lining of the anal canal does not. The place where the perianal skin (which has squamous cells plus hair follicles and sweat glands) meets the anal canal (which has squamous cells without hair follicles or sweat glands) is called the anal margin or anal verge. Cancers of the anal canal (above the anal verge) and cancers of the anal margin (below the anal verge) are treated very differently.
The anal canal is surrounded by a sphincter, which is a circular muscle that keeps feces from coming out until it is relaxed during a bowel movement.

Anal tumors

Many types of tumors can develop in the anus. Not all of these tumors are cancers -- some are benign (non-cancerous). There are also some growths that start off as benign but over time can develop into cancer. These are called pre-cancerous conditions. This section discusses all of these types of abnormal growths.

Throat Cancer

Throat cancer refers to cancerous tumors that develop in your throat (pharynx), voice box (larynx) or tonsils.
Your throat is a 5-inch-long muscular tube that begins behind your nose and ends in your neck. Your voice box sits just below your throat and is also susceptible to throat cancer. The voice box is made of cartilage and contains the vocal cords that vibrate to make sound when you talk. Throat cancer can also affect the piece of cartilage (epiglottis) that acts as a lid for your windpipe. Tonsil cancer, another form of throat cancer, affects the tonsils which are located on the back of the throat.
You can reduce your risk of throat cancer by not smoking, not chewing tobacco and limiting alcohol use.

Symptoms of Throat Cancer

Signs and symptoms of throat cancer may include:

• A cough
• Changes in your voice, such as hoarseness
• Difficulty swallowing
• Ear pain
• A lump or sore that doesn't heal
• A sore throat
• Weight loss

When to see a doctor

Make an appointment with your doctor if you notice any new signs and symptoms that are persistent. Most throat cancer symptoms aren't specific to cancer, so your doctor will likely investigate other more common causes first.

Causes of Throat Cancer

Throat cancer occurs when cells in your throat develop genetic mutations. These mutations cause cells to grow uncontrollably and continue living after healthy cells would normally die. The accumulating cells can form a tumor in your throat.
It's not clear what causes the mutation that causes throat cancer. But doctors have identified factors that may increase your risk.

Types of throat cancer

• Throat cancer is a general term that applies to cancer that develops in the throat (pharyngeal cancer) or in the voice box (laryngeal cancer). The throat and the voice box are closely connected, with the voice box located just below the throat. More specific terms to describe the types of throat cancer include:

• Nasopharyngeal cancer begins in the nasopharynx — the part of your throat just behind your nose.

• Oropharyngeal cancer begins in the oropharynx — the part of your throat right behind your mouth that includes your tonsils.

• Hypopharyngeal cancer (laryngopharyngeal cancer) begins in the hypopharynx (laryngopharynx) — the lower part of your throat, just above your esophagus and windpipe.

• Glottic cancer begins in the vocal cords.

• Supraglottic cancer begins in the upper portion of the larynx and includes cancer that affects the epiglottis, which is a piece of cartilage that blocks food from going into your windpipe.

• Subglottic cancer begins in the lower portion of your voice box, below your vocal cords.

Mesothelioma Compensation

The compensation for each mesothelioma claim can be quite different depending on how well you make your case. A well structured case will aim to get you compensation for pain and suffering, lost wages, medical expense and support for loved ones. How soon you can expect to receive compensation depends on the case. In circumstances where a manufacturer is no longer in business, those companies have been forced to set up trust funds to pay for asbestos-related claims.

Sometimes a company that is being sued in asbestos-related lawsuit will decide that settling a claim is cheaper and less public than incurring the hundreds of thousands of dollars in legal fees that a court case would require. For the client, i.e. you, your mesothelioma lawyer only gets paid if you are successful. However, a defendant’s attorney is paid monthly throughout the entire process, regardless of the outcome.
In cases where both parties wish to settle, compensation can happen very quickly. While court cases tend to be more drawn out, and go on for months or even years. It is important for both cases to be pursued if for no other reason than to shed light on possible offenders who are yet to be identified. And even if a case does go to trial, the company/defendant can choose to negotiate a settlement partway through, especially if the case seems to be favoring the plaintiff. Settlements are also beneficial to you as the plaintiff because your lawyer will eventually be paid for his time and the less time he works on your case the less you have to pay him.
Mesothelioma Compensation Lawsuits Available to You
In cases where your illness was the result of exposure to asbestos while you were on the job, then you could very well have a personal injury case to make, and the opportunity to receive fair compensation for your injuries.


If a loved one has passed from an asbestos-related illness like Mesothelioma, you have the ability to file a wrongful death lawsuit, which is obviously more severe and can result in more extreme penalties. In most cases, attorneys typically file lawsuits against the manufacturer(s) of these asbestos products, not the employers or homeowners of homes where you might have worked and contracted the harmful material. These manufacturers are almost always held liable and accountable in court. In most cases, they were acutely aware of the health risks induced by by their products.
Veteran Claims and Services
Many veterans who served during World War II, Korea and the Viet Nam wars were exposed to high levels of asbestos. These veterans have the right to file a claim with the VA seeking compensation for any injuries or illnesses they’ve experienced as a result of exposure to asbestos while serving their country. However, the paperwork can be complicated and confusing. Should you need help, the Mesothelioma Center’s Veterans Assistance Department offers free guidance with filing these specific claims.

Curative Mesothelioma Surgery: Pleurectomy-Decortication

Despite decades of research and medical development, mesothelioma remains an incurable disease in medical communities. Because of this, emphasis is placed primarily on early detection, management therapies, and means to prevent public inhalation of asbestos (since mesothelioma is directly caused by asbestos exposure). Conventional cancer treatment is most often recommended, including chemotherapy, radiation, and surgical treatments. Mesothelioma lawyers highlight the curative potential of pleurectomy-decortication, a surgery used to extend survival and improve quality of life.
The most efficient procedures for such a surgery are widely debated, partly because it is still considered a radical treatment, and partly because such a small number of people have undergone the surgery. Pleurectomy-decortication is recommended for patients in the initial stages of mesothelioma and is one of two major curative surgeries. The other, extrapleural pneumonectomy, completely removes the affected lung and surrounding tissue.
Most medical experts and mesothelioma patients prefer pleurectomy-decortication because it spares the lung. The surgery does remove the affected membrane lining of the lung along with the mesothelioma tumors, however, because mesothelioma tumors are especially interconnected with healthy tissues, the operation can prove extremely difficult.
For the past two years, Dr. Robert E. Cameron, Director of the UCLA Mesothelioma Comprehensive Research Program, has held a symposium to discuss pleurectomy-decortication and other lung-sparing therapies. The symposium is attended by the world's top experts who aim to advance the treatment of mesothelioma.
A study by the Memorial Sloan-Kettering Cancer Center in New York examined the efficacy of both mesothelioma curative surgeries. They performed a multi-institutional study to increase statistical power to detect significant differences in outcome between the two. From 1990 to 2006, over 660 patients underwent resection at 3 separate institutions. The operative mortality was 7% for extrapleural pneumonectomy, and 4% for pleurectomy-decortication.
The study concluded that patients who underwent pleurectomy-decortication had better survival than those who underwent extrapleural pneumonectomy; however, the reasons are multifactorial and subject to selection bias. They recommended that, at present, the choice of resection should be tailored to the extent of the disease, any other diseases the patient might have, and type of multimodality therapy planned.
The parietal pleuron is the initial target during pleurectomy-decortication, including its surrounding area. The diaphragm is often removed in this process as it is one of the first places mesothelioma spreads to. Next, the surgeon attempts decortications of the lung, which entails removal of the visceral pleura and membrane of the lung. At this point a number of issues can interfere with complete cancer removal, including the inability to separate the affected areas safely from the lung. As previously mentioned, mesothelioma tumors are significantly entwined with healthy tissue, so surgery of this magnitude is often compromised by the danger of removing or damaging the healthy, necessary tissue. Any manipulation of the visceral pleura poses the risk of damaging the lung, so doctors must balance this risk during surgery.
After the tumor removal, a reconstructive process is necessary to ensure adequate lung function. If the diaphragm or other organs were removed, doctors must reconstruct the original structure. Following this, drainage tubes are inserted in various places to aid in fluid diffusion, proper lung expansion and retraction, and patient recovery. After final reconstruction procedures, the patient is moved to intensive care for a few days of monitoring, followed by rehabilitation and post-operative healing.

As with all surgeries, especially of this magnitude, some complications may occur during, before or after treatment. Pleurectomy-decortication is designed for patients with locally-contained mesothelioma, though it has been administered as a palliative treatment in some cases. Researchers suggest that future clinical trials should stratify for histological type and must consider the impact of type of surgical resection on the pattern of relapse.
Ultimately, the choice to undergo conventional mesothelioma treatments is an individual or familial decision. Mesothelioma attorneys understand the devastating nature of this disease and are available to help with any questions or concerns relating to its treatment, causes, or available legal options.
