What is the difference between stage 2 and stage 3 colon cancer?
Stage 2 cancers have spread outside the outer layers of the colon or into organs and tissues next to the colon. They do not involve surrounding lymph nodes. They may be either T3N0M0 or T4N0M0. T3 tumors have grown into the outer layers of the bowel wall but do not extend through it.
What is Stage 3A colon cancer?
Stage 3 colorectal cancer Stage 3A: The cancer has spread through the first two inner layers of the colon or rectum wall (mucosa and submucosa) and may have also reached the third layer (muscularis propria).

What is Stage 2 colon cancer mean?
Stage II colorectal cancer. In stage IIA, cancer has spread through the muscle layer of the colon/rectum wall to the serosa. In stage IIB, cancer has spread through the serosa of the colon/rectum wall to the visceral peritoneum (tissue that lines the organs in the abdomen).
What is Stage 3B colon cancer?
Stage 3B The cancer has grown into the wall of the colon or rectum or through the visceral peritoneum (the inner lining of the abdominal cavity) but has not reached nearby organs. It has spread to 1 to 3 nearby lymph nodes or into areas of fat near the lymph nodes but not to distant sites (T3 or T4a, N1/N1c, M0).
Is chemo necessary for stage 3 colon cancer?

Can you survive stage 3a colon cancer?
We evaluated 34,999 patients diagnosed with stage IIIA or stage IIB/C colon cancer in 2003–2012 from the National Cancer Data Base. The 5-year overall survival (OS) was 73.5 % for stage IIIA and 51.1 % for stage IIB/C (P < 0.0001).

Stage II adenocarcinoma of the colon is a common and curable cancer. Depending on features of the cancer, 60-75% of patients are cured without evidence of cancer recurrence following treatment with surgery alone. Stage II cancer can be further divided into two stages, Stage IIA and Stage IIB.
Can you survive Stage 2 colon cancer?
Stage II disease falls somewhere in between. An estimated 75% of people with stage II colon cancer will be cancer-free 5 years later, without adjuvant chemotherapy, but 25% will not. Some of these patients may benefit from having chemotherapy after surgery.
Is stage 3b cancer curable?
Stage IIIB NSCLC has not historically been considered curable, but advances in treatment including the development of new chemotherapy drugs and targeted therapies are prolonging survival and reducing cancer symptoms well beyond what was expected just a few years ago.
What is the best treatment for stage 3 colon cancer?
Does stage 3 colon cancer need chemo?
Is chemo needed for Stage 2 colon cancer?

CCD Orlando: If you are diagnosed with colorectal cancer, it is not a death sentence unless you wait too long.
How often does Stage 2 colon cancer come back?
The results of this study, analyzing the data of a total of 871 patients with stage II colon cancer, demonstrated a five-year recurrence rate of 10%. Most recurrences occurred in the first two years after surgery.
What is TNM staging in colon cancer?
TNM Staging. Tumour, node and metastasis (TNM) staging is one of the systems used to stage bowel (colon and rectal) cancer. Doctors may also use the number staging or the Duke’s staging system.

What do the N and m mean on a tumor map?
The main tumor is usually called the primary tumor. The N refers to the the number of nearby lymph nodes that have cancer. The M refers to whether the cancer has metastasized. This means that the cancer has spread from the primary tumor to other parts of the body.
