Question 1

What is malignant tumor?

Accepted Answer

Cancer involves the uncontrolled growth of abnormal cells that have mutated from normal tissues. This growth can kill when these cells prevent normal function of vital organs or spread throughout the body, damaging essential systems.

Question 2

What are the risk factors for malignant tumor?

Accepted Answer

There are many different kinds of cancers. Cancer arises out of normal cells in the body, and can develop in almost any organ or tissue, such as the lung, colon, breast, skin, bones, or nerve tissue. In general, cancer appears to be caused by abnormal regulation of cell division. Cancers can occur when cells divide too rapidly or when cells "forget" how to die. There are multiple causes of cancers such as: • Radiation • Sunlight • Tobacco • Certain viruses • Benzene • Certain poisonous mushrooms and aflatoxins (a poison produced by organisms that can grow on peanut plants) However, the cause of many cancers remains unknown. The three most common cancers in men in the U.S.

Question 3

What are the symptoms of malignant tumor?

Accepted Answer

Symptoms of cancer depend on the type and location of the tumor. For example, lung cancer can cause coughing, shortness of breath, or chest pain, while colon cancer often causes diarrhea, constipation, and blood in the stool. Some cancers may not have any symptoms at all. However, the following symptoms are common with most cancers: • Fever • Chills • Night sweats • Weight loss • Loss of appetite • Fatigue • Malaise

Question 4

How is malignant tumor treated?

Accepted Answer

Treatment also 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 goal for treatment would be surgery and cure. This is often the case with skin cancers. • If the tumor has spread to local lymph nodes only, sometimes these can also be removed. • If all of the cancer cannot be removed with surgery, the options for treatment include radiation, chemotherapy, or both. Some cancers require a combination of surgery, radiation, and chemotherapy.

Question 5

What is the outlook for malignant tumor?

Accepted Answer

The outlook varies widely among different types of cancer. Even among people with one particular type of cancer, the outcome varies depending on the stage of the tumor at diagnosis. Some cancers can be cured, some that are not curable can still be treated well, and some patients can live for many years with the cancer. Other tumors are rapidly fatal.

Question 6

What are the complications of malignant tumor?

Accepted Answer

One complication is that the cancer may spread. Other complications vary with the type and stage of the tumor.

Question 7

Can malignant tumor be prevented?

Accepted Answer

One of the best ways to prevent cancer is to not smoke or chew tobacco. Many cancers can be prevented by avoiding risk factors such as excessive exposure to sunlight and heavy drinking. Cancer screenings, such as mammography and breast examination for breast cancer and colonoscopy for colon cancer, may help catch these cancers at their early, most treatable stages. Some people at high risk for developing certain cancers can take medication to reduce their risk.
