Treatment for colon cancer generally depends on the degree of cancer, but other elements can likewise be significant. Most of the time, surgery is the main form of treatment and results in a cure in roughly half of the patients. Colon or colorectal cancer can be detected by a dental checkup. Schedule an appointment with your dentist to identify other major health complications. In any case, in this article, you will know the different treatments of colon cancer according to its various stages.

What is Colorectal Cancer?

Colon cancer is a tumor that starts in the colon, while rectal cancer is cancer in the rectum. Cancers that influence both colon and rectum might be called colorectal cancer. However, most colorectal cancers usually occur after some time from precancerous polyps. Polyps can evolve after a progression of transformations arises in their cellular DNA. A portion of the risk factors for this cancer involves a family history of colorectal cancer, alcohol intake, diet, smoking, and inflammatory bowel disease.

Types of Treatment

Scientists and doctors are always looking for better approaches to care for cancer patients. To make scientific advances, they make research studies incorporating volunteers, called clinical trials. Nowadays, clinical trials are used to treat all types and stages of colorectal cancer.

In addition to this, patients with colon cancers that have not spread to far-off sites frequently have surgery as the principal or first treatment. The doctor may also utilize chemotherapy after surgical treatment.

The following are the different treatments depending on the extent of the condition of the patients.

Stage 0

Phase 0 colon cancers have not developed past the inner covering of the colon. Hence, surgery to remove the tumor is frequently the only treatment necessary. A doctor can complete this most of the time by taking out polyp or removing the portion with cancer through a colonoscope. Eliminating part of the colon or partial colectomy might be necessary if the tumor is too enormous for the surgeon to remove it by local extraction.

Stage I

A stage I colon cancer has become further into the layers of the colon wall. Yet, this phase does not advance outside the colon wall itself or into the close lymph nodes.

This stage includes cancers that were part of a polyp. Suppose the doctor eliminated the polyp during colonoscopy, with no disease cells at the edges of the removed element. In that case, no other treatment for colorectal cancer might be necessary. If there are cancer cells at the lining of the polyp or cancer in the polyp is high grade, more surgery may be essential. Patients may likewise get more surgery if the surgeon cannot remove them totally. Or if it must be eliminated in numerous pieces, making it difficult to check whether cancer cells were at the margins. For partial colectomy, surgery is the standard treatment to eliminate the part of the colon that has cancer and is close to lymph glands. Typically, patients will not require any more treatment.

Stage II

Numerous stage II colon cancers have developed through the colon wall and possibly into nearby tissue. Still, they have not extended to a lymph node.

Medical procedure to eliminate the section of the colon containing cancer alongside nearby lymph nodes might be the only treatment required. However, your doctor may suggest adjuvant chemotherapy if your cancer has a greater danger of recurring because of some factors, such as:

• Cancer appears extremely unusual or high grade when seen closely in the lab.
• The tumor develops into nearby lymph or blood vessels.
• Cancer in or near the edge of the eliminated tissue implies that some cancer may have been abandoned.
• The surgeon did not eliminate at least 12 lymph glands.
• Cancer caused a hole in the wall of the colon.
• Cancer had obstructed the colon.

The doctor may likewise test your cancer for explicit gene transformations, called MMR or MSI, to help choose if adjuvant chemotherapy would be beneficial. Not all specialists concur on when chemo should be essential for stage II colon cancers.

You must examine the risks and advantages of chemo with your doctor, including the amount it may diminish your danger of recurrence and what the possible side effects will be.

If the doctor recommends chemo, most treatment options incorporate 5-FU and leucovorin, capecitabine, or oxaliplatin. However, they may also use different combinations.

Stage III

A stage III colon cancer has spread to close lymph nodes. However, this level does not yet progress to different parts of the body.

This treatment surgically removes colorectal cancer alongside nearby lymph glands, followed by adjuvant chemo.

Additionally, neoadjuvant chemotherapy may offer along with radiation, especially for some advanced colorectal cancers that a surgeon cannot remove entirely by surgery. Surgeons perform this to shrink cancer so they can eliminate it later with surgical procedures. On the other hand, adjuvant radiation may suggest if advanced cancers surgically removed were discovered to be joined to a close-by organ or have positive edges. Chemotherapy and radiation therapy might be possibilities for individuals who are not healthy enough for colon cancer surgery.

Stage IV

It is the stage of cancer that has spread from the colon to far-off organs and tissues. Colorectal cancer regularly spreads to the liver. However, it can likewise progress to different areas such as the brain, lungs, peritoneum, or distant lymph nodes.

In most cases, surgery is probably not going to treat colorectal cancer of this stage. Yet, if some small areas of cancer spread in the lungs or liver and the surgeon can remove them along with the colon cancer, the procedure may help you live longer. Additionally, doctors will give you chemo after surgery. Sometimes, they may use hepatic artery infusion if cancer progresses to the liver.

If colorectal cancer progresses too much to address with surgery, then chemo is the primary therapy. A surgical procedure may still be necessary if the tumor is hindering the colon or will probably do as such. At times, you can avoid such surgery by putting a stent into the colon during a colonoscopy to keep it open.

Once you have stage IV colorectal cancer and your physician suggests surgery, it is essential to comprehend the procedure’s objective. Know whether it is to attempt to address the condition or forestall or relieve symptoms of cancer.
