1.Disorders of the gastrointestinal tract: chronic constipation or diarrhea, change in the number and color.
All this may mean colon cancer. When you have painful urination, blood in the urine, you should immediately go to the doctor. Very common urination, without obvious cause, may be a symptom of prostate cancer.

2. The appearance of wounds and ulcers. Often the tumor is “masked” like an ulcer, but it’s bleeding very much. Small wounds in the mouth, which are not treated – can also be cancer. Changes on the v*gina or p*nis, except for talking about a serious infection of the body, can also be cancer of the genital organs.

3.Blood. Quite often in the case of blood, means the cancer is already in an advanced stage – the disease has developed, and you have it for a very long time. Pushing bloodthirsty – there is a high chance of lung cancer, and if the blood is found in your toilet – colon cancer. Blood-flowing or secretion with a pus of grain – a direct sign of breast cancer.
