The reason cancer happens in some people is the cancer is caused by cells that divide uncontrollably and spread into surrounding tissues.

And cancer is is caused by changes to DNA and most cancer-causing DNA changes occur in sections of DNA called genes and these changes are also called genetic changes.

The first sign of cancer is usually Continued itching in the anal or genital area, blood in the urine, unexpected weight loss, night sweats, or fever, unusual vaginal bleeding or discharge, indigestion or difficulty swallowing, obvious change in a wart or a mole, persistent lumps or swollen glands and hoarseness.

Cancer is a group of diseases involving abnormal cell growth with the potential to invade or spread to other parts of the body. These contrast with benign tumors, which do not spread.

There are several different types of cancer which include.

Skin Cancer, Brain Cancer, Brain Tumor, Breast Cancer, Prostate Cancer, Basal Cell Cancer, Melanoma Cancer, Bowel Cancer, Bladder Cancer, Colon Cancer, Lung Cancer, Leukemia Cancer, Renal Cancer, Kidney Cancer, Lymphoma Cancer.

The signs and symptoms of the cancers depend on the type of cancer you may have or have.

Most cancers can be cured if caught and treated soon enough through radiation therapy and chemotherapy and surgeries to remove the cancer.

The longer the cancer is left untreated the less chance you have at being cured of it but the sooner you catch the cancer before it spreads the more chance you have at curing the cancer.
