Gastrointestinal cancer: Gastrointestinal cancer starts in the inner lining walls of the gastrointestinal tract. Gastrointestinal tract is comprised of gallbladder, liver, esophagus, small intestine, pancreas, stomach, large intestine (colon) and rectum. Gastrointestinal cancer refers to the cancer of entire digestive system.

Cells plays major role in defining cancer. All the organs and tissues in the body are made up by tiny body cells. These cells have a constant process of dying and replacing new cells. This is the general process carried by them, if there is any malfunction in their life cycle then there is a chance for the occurrence of cancer. Tumor occurs due to the formation of excess cells in the body. There are two types of Tumors one is benign tumor and the other is malignant tumor .Benign tumor is not cancerous but can cause damage to the adjacent organs if it grows continuously at a single site. Malignant tumor is cancerous because it spreads through out the body and damages the entire body organs.

Here is the list of gastrointestinal cancer:
• Gallbladder
• Liver
• Esophagus
• Small intestine
• Pancreas
• Stomach
• large intestine (colon)
• Rectum

Risk factors of gastrointestinal cancer:
• Age
• Gender
• Smoking
• Alcohols
• Family pedigree
• External beam radiation
• Infection of parasites
• Urinary stones
• Inflammation of bladder
• High saturated fat foods
• Diet and food intake

Symptoms of gastrointestinal cancer:
• Blood in the urination
• Urination pain
• Regular feel of urination
• Infections
• Bladder stones
These are the symptoms and signs for the bladder cancer.

Treatments for gastrointestinal cancer:
There are total four types of treatment available for gastrointestinal cancer, they are:

Surgery: surgery is the common of type of treatment available for removing the tumor. The kind of treatment is decided well by the doctor. They are total three types of surgeries which can be carried by identifying the severity of the cancer.

Transurethral resection: This kind of treatment is carried by inserting a cystoscope into the urethra and from there the tumor is removed by using some tools. After that the affected area is burned to kill the remaining cancer cells by using electric current, this process is called as fulguration. Radical cystectomy: This surgery is carried for treating invasive bladder cancer. In this treatment the entire bladder is removed along with the adjacent effected organs for stopping spreading of the disease. Segmental cystectomy: This treatment process is useful in removing the only effected part in the colon. This operation is carried to clear the entire effected part of the bladder.

Chemotherapy: Chemotherapy is one of the treatment methods useful in killing cancer causing cells by the usage of drugs. This treatment process is carried by either pills or through intravascular injections. The anti-cancer drug enters into the bloodstream and travels towards the damaged tissues and destroys the cancer cells. Chemotherapeutic drugs attacks the gastrointestinal cancer cells by stopping their unusual growth. The nature of the cancer cells were brought to the normal condition by controlling the divisibility of the cells. These drugs are carried in the bloodstream to kill destroy all the cancer cells within short period of time.

Radiotherapy: Radiotherapy is a useful process of removing gastrointestinal cancer cells by using high intensity x-rays. These high energy x-rays are aimed at the cancer affected part of the body to destroy the cancer cells. This process also causes damage to the normal cells for its side effects. There are two types of radiotherapy treatments they are.

External radiations: Radiations are given from the external side of the body. The radiations are aimed at the effected area from outside the body. Internal radiations: Radiations are passed into the body by making some small incisions in the abdomen area. This treatment gives better results than the external radiation therapy.

Biotherapy: Due to weak immune system in the body, there are chances for the development of cancer. So this Biotherapy treatment process is useful in rebuilding strong immune system in the body. Biotherapy is also called as immunotherapy or biological response modifier therapy. This treatment process is really useful in repairing, enhancing and stimulating the weak immune system of the body. This process can be carried along with surgery, chemotherapy and radiotherapy.

Gastrointestinal cancer is treated as a serious problem due to its effects. All kinds of digestive cancers are together called as gastrointestinal cancer. This cancer affects nearly 30,000 people in a year. Gastrointestinal cancer cells are cancerous because they spread to other parts in the body. The treatment for gallbladder, liver, esophagus, small intestine, pancreas, stomach, large intestine (colon) and rectum cancer is same.This cancer alaso causes gynecologic cancer due to metastatic cancer cells.
