When the healthy cells in the lining of the colon or rectum grow out of control forming a mass of extra and unwanted bulge, then it can be called colorectal cancer. This may be genetic but mostly it is due to environmental factors or an uncommon inherited syndrome. The tumor begins as a polyp and becomes life-threatening if not detected during the beginning. Symptoms such as a change in eating habits, blood in the stool, discomfort while sitting, anemia, tiredness, and weight loss may be seen in a person suffering from first-stage colorectal cancer.

In these types of chemotherapy, the drug is directly injected into the veins, given orally, or directly injected into the artery which passes through the bloodstream. Adjuvant chemo and neoadjuvant chemo are other forms of chemotherapy performed at different times.

Nowadays there are several new methods to diagnose cancer. The diagnosis is usually made by pathologists, oncopathologists, or radiologists. There are a number of medical gadgets available today that can help to diagnose cancer in a better way. The first step in diagnosing cancer is the use of imaginary techniques such as X-rays, MRI scans, and ultrasound scans. This is the basic step to diagnose the location of the tumor and the organ affected by the tumor. Furthermore, the doctors may conduct an endoscopy which is an imaginary technique in which a thin tube with a tiny camera is inserted in the affected part of the body. This will allow the medical specialists to check the affected area thoroughly.
The doctors may conduct a biopsy in which a small sample of tissue is taken with the help of a fine-tipped needle. After the biopsy, the sample will be sent for a lab test in which the sample will be checked under a microscope to diagnose whether it’s cancer or not. Other tests include the blood test and PAP test. After the diagnosis, the doctors may suggest the treatment which is based on the cancer stage and grade. There are different types of stages in cancer which are termed as TNM (0-4) where zero is considered as the early stage of cancer while the level 4 tumor is considered as a late stage of cancer, hence untreatable.
