Anal Cancer

Anal cancer occurs in the anus, the end of the gastrointestinal tract. Anal cancer is very different from colorectal cancer, which is much more common. Anal cancer's causes, risk factors, clinical progression, staging and treatment are all very different from colorectal cancer. Anal cancer is a lump which is created by the abnormal and uncontrolled growth of cells in the anus. Anal cancer is very rare.

Symptoms of anal cancer:

    Rectal bleeding - the patient may notice blood on feces or toilet paper.
    Pain in the anal area.
    Lumps around the anus. These are frequently mistaken for piles (hemorrhoids).
    Mucus discharge from the anus.
    Jelly-like discharge from the anus.
    Anal itching.
    Change in bowel movements. This may include diarrhea, constipation, or thinning of stools.
    Fecal incontinence (problems controlling bowel movements).
    Women may experience lower back pain as the tumor exerts pressure on the vagina.
    Women may experience vaginal dryness.

Liver Cancer

The liver continuously filters blood that circulates through the body, converting nutrients and drugs absorbed from the digestive tract into ready-to-use chemicals. The liver performs many other important functions, such as removing toxins and other chemical waste products from the blood and readying them for excretion. Because all the blood in the body must pass through it, the liver is unusually accessible to cancer cells traveling in the bloodstream.

The liver can be affected by primary liver cancer, which arises in the liver, or by cancer which forms in other parts of the body and then spreads to the liver. Most liver cancer is secondary or metastatic, meaning it started elsewhere in the body.

Because the liver is made up of several different types of cells, several types of tumors can form there. Some of these are benign (noncancerous), and some are cancerous and can spread to other parts of the body (metastasize). These tumors have different causes and are treated differently.
