  • 1. Cancer is the uncontrolled growthof abnormal cells in the body.Cancerous cells are also calledmalignant cells.
  • 2. • Cancer grows out of normal cells in the body. Normal cells multiply when the body needs them, and die when the body doesnt need them. Cancer appears to occur when the growth of cells in the body is out of control and cells divide too quickly. It can also occur when cells forget how to die.• There are many different kinds of cancer. Cancer can develop in almost any organ or tissue, such as the lung, colon, breast, skin, bones, or nerve tissue.• There are many causes of cancer, including: • Benzene and other chemicals • Drinking excess alcohol • Environmental toxins, such as certain poisonous mushrooms and a type of poison that can grow on peanut plants (aflatoxins) • Excessive sunlight exposure • Genetic problems • Obesity • Radiation • Viruses
  • 3. • Prostate cancer• Lung cancer• Colon cancer• Breast cancer• Colon cancer• Lung cancer• Brain cancer• Cervical cancer• Hodgkins lymphoma• Kidney cancer• Leukemia• Liver cancer• Non-Hodgkins lymphoma• Ovarian cancer• Skin cancer• Testicular cancer• Thyroid cancer• Uterine cancer
  • 4. • Symptoms of cancer depend on the type and location of the cancer. For example, lung cancer can cause coughing, shortness of breath, or chest pain. Colon cancer often causes diarrhea, constipation, and blood in the stool.• Some cancers may not have any symptoms at all. In certain cancers, such as pancreatic cancer, symptoms often do not start until the disease has reached an advanced stage.• The following symptoms can occur with most cancers: • Chills • Fatigue • Fever • Loss of appetite • Malaise • Night sweats
  • 5. • Like symptoms, the signs of cancer vary based on the type and location of the tumor. Common tests include the following: • Biopsy of the tumor • Blood tests (which look for chemicals such as tumor markers) • Bone marrow biopsy (for lymphoma or leukemia) • Chest x-ray • Complete blood count (CBC) • CT scan • Liver function tests • MRI scan• Most cancers are diagnosed by biopsy. Depending on the location of the tumor, the biopsy may be a simple procedure or a serious operation. Most patients with cancer have CT scans to determine the exact location and size of the tumor or tumors.• A cancer diagnosis is difficult to cope with. It is important, however, that you discuss the type, size, and location of the cancer with your doctor when you are diagnosed. You also will want to ask about treatment options, along with their benefits and risks.• Its a good idea to have someone with you at the doctors office to help you get through the diagnosis. If you have trouble asking questions after hearing about your diagnosis, the person you bring
  • 6. • Treatment varies based on the type of cancer and its stage. The stage of a cancer refers to how much it has grown and whether the tumor has spread from its original location. • If the cancer is confined to one location and has not spread, the most common treatment approach is surgery to cure the cancer. This is often the case with skin cancers, as well as cancers of the lung, breast, and colon. • If the tumor has spread to local lymph nodes only, sometimes these can be removed. • If surgery cannot remove all of the cancer, the options for treatment include radiation, chemotherapy, or both. Some cancers require a combination of surgery, radiation, and chemotherapy. • Lymphoma, or cancer of the lymph glands, is rarely treated with surgery. Chemotherapy and radiation therapy are most often used to treat lymphoma.• Although treatment for cancer can be difficult, there are
  • 7. • If you have radiation treatment, know that: • Radiation treatment is painless. • Treatment is usually scheduled every weekday. • You should allow 30 minutes for each treatment session, although the treatment itself usually takes only a few minutes. • You should get plenty of rest and eat a well-balanced diet during the course of your radiation therapy. • Skin in the treated area may become sensitive and easily irritated. • Side effects of radiation treatment are usually temporary. They vary depending on the area of the body that is being treated.• If you are going through chemotherapy, you should eat right. Chemotherapy causes your immune system to weaken, so you should avoid people with colds or the flu. You should also get plenty of rest, and dont feel as though you have to accomplish tasks all at once.• It will help you to talk with family, friends, or a support group about your feelings. Work with your health care providers
  • 8. • You can reduce the risk of getting a cancerous (malignant) tumor by: • Eating a healthy diet • Exercising regularly • Limiting alcohol • Maintaining a healthy weight • Minimizing your exposure to radiation and toxic chemicals • Not smoking or chewing tobacco • Reducing sun exposure, especially if you burn easily• Cancer screenings, such as mammography and breast examination for breast cancer and colonoscopy for colon cancer, may help catch these cancers at their early stages when they are most treatable. Some people at high risk for developing certain cancers can take medication to reduce their risk.
