Benefits of Bevacizumab
Cancer of colon and rectum
Cancer of the colon and rectum, also known as colorectal cancer (CRC) or bowel
cancer, is the development of cancer from two parts of the large intestine,
namely, the colon or rectum. In this type of cancer, the person may notice
symptoms such as blood in the stool, a change in bowel movements, weight loss,
and fatigue. Bevacizumab treats and also lowers the risk of developing further
cancerous growths (polyps) and bowel cancer. It kills or stops the growth of
cancer cells and also prevents the multiplication of cancer cells. It is an
effective, yet very toxic medicine and you should discuss the risks and
benefits with your doctor.
Non-small cell lung cancer
Non-small cell lung cancer is one of the major kinds of lung cancer and it
affects both smokers as well as non-smokers. Bevacizumab helps treat non-small
cell lung cancer and may be given alone or in combination with other
medicines. It is a potent and very toxic medicine and you should discuss the
risks and benefits with your doctor. You should avoid drinking alcohol or
smoking while having this treatment and drink plenty of water to stay
hydrated.
Kidney cancer
Bevacizumab is used to treat kidney cancer and its associated symptoms such as
blood in the urine, unexplained low back pain or weight loss, fatigue, loss of

(malignant) or non-cancerous (benign). Bevacizumab kills or stops the growth of

cells. It is an effective medicine but has some side effects that may be
