There are two main types of lung cancer: non-small-cell lung cancer and small-cell lung cancer. Non-small-cell lung cancer accounts for about 80% of lung cancers. They include a heterogeneous group of cancers that grow and spread less rapidly than small-cell lung cancer. By contrast, small-cell lung cancer accounts for 20% of all lung cancers. Although the cells are small, they multiply quickly and form large tumors that can spread throughout the body.

There are different kinds of eye cancers. Below are some of the places near or on the eye where cancers can grow and the types that may be present on each one of these places: Eyelid tumors. Basal cell carcinoma is the most common type of eyelid cancer. It can be removed with surgery. Other types of eyelid tumors include squamous cell carcinoma, sebaceous cell carcinoma, and malignant melanoma. Tumors that grow on the surface of the eye (conjunctival tumors).

Lung cancer is the most frequently occurring cancer in the US, accounting for 30% of all diagnosed cancer. The largest number of asbestos related deaths occurs from lung cancer. Most lung cancer caused by asbestos inhalation starts in the lining of the bronchi, the tubes that lead from the windpipe into each lung. Lung cancer caused by asbestos exposure can also begin in the windpipe itself, the bronchioles, smaller tubes which branch off from the bronchi, or in the alveoli.

Statistics are compiled from the experiences of large numbers of people and therefore, are best interpreted in a general way, with the understanding that individuals may have different experiences.

The term, ovarian cancer, is used to refer to a malignancy of the outer lining or epithelium of the ovary. The most common subtype is called papillary serous carcinoma because of the frond-like appearance microscopically. The second most common subtype is endometrioid. Mucinous and clear cell carcinoma are less common subtypes and tend to have a poorer prognosis.

Basal cell carcinoma, squamous cell carcinoma, and melanoma are the three types of skin cancers. Basal cell carcinoma and squamous cell carcinoma are the most common types and less dangerous than melanoma. They usually occur on sun-exposed areas of the body such as the face, neck and hands. Melanoma is the most serious because if it is not treated early, it is more likely to spread throughout the body.

A doctor makes a prognosis based on many factors, including the specific type of cancer, its stage, and the general health and age of the patient. Doctors carefully gather as much information as they can before they make a prognosis. However, a second opinion may provide additional information. Cancers are classified into stages in order provide guidance for treatment decisions.

Research shows that there are some immediate health benefits of quitting smoking, including enhanced circulation and lowered blood pressure. Quitting smoking after a diagnosis of lung cancer can help your body better cope with the treatment you are about to undergo.

Patients with advanced lung cancer who receive chemotherapy generally have an improved quality of life and tend to live longer than those who do not undergo drug therapy. Clinical studies have shown that patients on drug therapies for late stage lung cancer experience fewer days in the hospital and have fewer and less severe symptoms from their disease.

It's the leading cause of cancer death in both men and women in the U.S. More people die of lung cancer than colon, breast, and prostate cancers combined. According to the American Cancer Society, there will be about 174,470 new cases of lung cancer in 2006 including 92,700 in men and 81,770 in women. A woman's chance of developing lung cancer is one in 17, while a man's chance is one in 13. Black men are more likely to develop lung cancer than white men.

The March 2006 death of nonsmoker Dana Reeve, the widow of Superman actor Christopher Reeve, from lung cancer shed some light on this issue. It turns out that more than 60% of new lung cancer patients have never smoked or already have quit smoking, says the Lung Cancer Alliance. In some of these people, exposure to secondhand smoke may actually be a culprit. Reeve, for example, a lounge singer, performed in some very smoky clubs. So in short, yes nonsmokers can -- and do -- get lung cancer.

Surgery to remove the tumor, radiation (X-rays that kill or shrink cancer cells directed at the site of the tumor) , chemotherapy (systemic drugs that kill all fast-growing cells in the body including cancer cells) and potentially experimental treatments are all part of your doctors tool box for lung cancer treatment. Before deciding on which treatment or combination of treatments is right for you, your doctor will have to determine how advanced your lung cancer is.

The best way to prevent lung cancer is not to smoke and to avoid breathing in other people's smoke. If you smoke, quit. While the risk for former smokers remains elevated when compared to a nonsmoker, it continues to fall with each year of smoking cessation. In fact, after quitting for 10 years, an ex-smoker reduces their risk anywhere from 30% to 50%. Just do it! Eating a healthy diet loaded with fruits and vegetables may also help prevent the cancer.

You should talk to your doctor about this issue. Screening for lung cancer is controversial, because it can detect scars and other irregularities that may be mistaken for cancer. However, screening can find cancers when they are early, and therefore more treatable. The National Lung Screening Trial is examining whether screening with spiral computerized tomography or standard chest x-ray can reduce lung cancer deaths.

Adenocarcinoma is the most common kind of lung cancer. It usually happens more to women and to people who smoke. A lot of people with adenocarcinoma do not have symptoms, so it is difficult for doctors to find it early. Squamous cell carcinoma occurs in men more than women. This kind of cancer grows more slowly than the others and is the easiest for doctors to find. Large-cell carcinoma is the least common kind of lung cancer.

Depending on the extent of the cancer, the surgeon may decide to remove part or all of the lung. Taking out a part of the lung is called a segmental or wedge resection. If a lobectomy is performed, an entire lobe of the lung is removed. A pneumonectomy is the removal of an entire lung.

Four major treatments are widely used to combat cancer. These methods are surgery, radiation, chemotherapy, and immunotherapy (sometimes referred to as biological therapy). Surgery is the oldest method for treating cancer. It plays an important role in diagnosing and detecting the extent of cancer in the body. The newest method for treating cancer is immunotherapy, a process that relies on the body's immune system to combat the disease.

This is a question to ask your doctor. Even though treatment regimens have similarities, they are often tailored to the individual patient. Therefore, it is important you speak frankly with your doctor. Undergoing chemotherapy can be a scary experience, especially if you have heard that another treatment is better. However, your doctor made her recommendation based on your specific cancer and your general health and she has your best interest in mind.
