Symptoms Of Each Stage Of Colon Cancer – After skin and lung cancer, colon cancer is the third most common cancer reported in men and women in the United States. In 2021, 104,270 new cases of colorectal cancer and 45,230 new cases of rectal cancer were reported in the US, according to the American Cancer Society.
Overall, 1 in 23 men (4.3 percent) have a lifetime risk of colorectal cancer, while women have a lifetime risk of 1 in 25 (4.0 percent). To learn more and understand the risks associated with this disease, it is necessary to be informed about colon cancer and its causes.

Symptoms Of Each Stage Of Colon Cancer
Colon cancer starts in the large intestine and spreads throughout the body if not treated in time. Colon polyps are small collections of cells that grow on the inside of the colon, which are often the first signs of colon cancer. Some of these polyps may be benign, while others may turn into colon cancer over time.
Circulating Tumor Dna Analysis Detects Minimal Residual Disease And Predicts Recurrence In Patients With Stage Ii Colon Cancer
When a person is diagnosed with this cancer, specialists will try to determine how far it has spread. This is called staging.
Staging reflects how much cancer has developed in the body. It helps determine the severity of the disease and which treatment options are appropriate for the condition. Survival rates are also calculated after the cancer stage is confirmed.
The American Joint Committee on Cancer (AJCC) TNM method, based on three critical pieces of evidence, is a staging approach for colorectal cancer. The system uses the following parameters:
The inner layer (mucosa) that covers the colon or rectum has abnormal cells, even if it is not cancerous at this time.

Cancer that begins as a polyp is classified as stage I colon cancer. The inner lining of the colon or rectum contains abnormal cells that have spread to the second layer of tissue (the submucosa).
At this stage, the cancer may have spread to the adjacent muscle layer (muscularis propria), but the surrounding lymph nodes have not been affected.
Cancer has spread to the outer layer of the wall of the colon or rectum, but has not progressed.
Here, the cancer has spread beyond the outer layer of the colon or rectal wall, but not into the surrounding tissues or organs.

The cancer has spread beyond the outer layer of the wall of the colon or rectum, to nearby tissues or organs, but not to lymph nodes or distant major organs.
At this stage, the cancer has spread to the mucosal and submucosa layers of the colon or rectal wall, and may reach the third layer (muscularis propria). One or three nearby lymph nodes have also been affected, or abnormal cells have been found near the lymph nodes.
Or the cancer has spread to the next four after passing through the first two layers of the colon or rectal wall.
This means that the cancer has spread to the outer layer (serosa) of the wall of the colon or rectum. It may have reached the visceral peritoneum (the outer covering of organs suspended in the abdominopelvic cavity), which lines the abdominal organs, but has not yet reached the surrounding organs. One or three nearby lymph nodes are cancerous, or these cells have been identified near the lymph nodes.

Alternatively, the cancer has spread to the muscular or outer layer of the wall of the colon or rectum, affecting four or six nearby lymph nodes.
The cancer has spread beyond the wall of the colon or rectum and into the tissue that lines the abdominal organs, but not the surrounding organs. Four or six nearby lymph nodes have been reported to be cancerous.
Otherwise, the cancer has spread from the tissue surrounding the abdominal organs. It is identified in seven or more nearby lymph nodes.
At least one nearby lymph node has cancer, or damaged cells have been found near the lymph nodes.
What Are Signs And Symptoms Of Colon Cancer?
The cancer has spread to another part of the colon or rectum, or to a major organ such as the liver, lung, ovary, or distant lymph node.
Colon cancer treatment is mostly determined by its stage (percent spread), although other factors may also play a role. However, depending on the stage, the following are some common treatment options:
Stage 0 colon cancers have not migrated beyond the inner lining of the colon, so surgery to remove the tumor is usually the only option. If a lesion is too large to be removed by local excision, a partial colectomy (removal of part of the colon) may be recommended by cancer providers.
Cancers that started as polyps are identified through a test called a colonoscopy. If no abnormal cells are found at the edges of the cut piece, no further treatment is required. If the polyp cannot be removed further surgery will be recommended. Removal of the cancerous segment of the colon and surrounding lymph nodes is the standard treatment for non-polyp cancers.
Anal Cancer Vs. Colon Cancer: Symptoms, Causes, Treatment
Removing the region affected by the colon cancer and the nearby lymph nodes may be the only treatment needed. However, your doctor may suggest additional chemotherapy if there is more recurrence due to certain conditions.
The typical treatment at this stage is a surgical procedure to remove the cancerous part of the colon and nearby lymph nodes, before topical chemotherapy. For some severe colon cancers that cannot be removed by surgery, neoadjuvant chemotherapy combined with radiation may be used to then surgically remove the cancer. For those who are not yet healthy enough for surgery, radiation therapy and/or chemotherapy may be an option.

Surgery is not necessary to treat stage 4 cancer in most patients. On the other hand, surgery can help if there are specific areas where the cancer is, and they can be removed along with the colon cancer. This would require surgery to remove the area affected by the cancer. Chemotherapy treatment is given after surgery. If the disease has progressed to the liver, a hepatic artery infusion would be used in some situations.

Radiation treatment can help prevent or cure problems associated with colon cancer, such as discomfort. It can be used to treat areas where cancer has spread, such as the lungs or bones. It may shrink the tumors temporarily, but it is unlikely to fight the cancer. It is important to understand the goal of treatment if your doctor suggests radiation therapy.

Skin cancer develops in short ducts that leave your body. Colon cancer develops in the large intestine. Their symptoms and treatment are similar, but the causes are very different.
What Are The Treatment Options For Colon Cancer?
Anal cancer and colon cancer seem to affect the same system. While this is partly true, the location of the cancer in your body is just one of the main differences between these two cancers.
This article will look at some of the similarities and differences in the symptoms, causes and views of people with anal and colon cancer.
Anal cancer develops in the lower part of your large intestine. Your anus contains only a short channel through which feces leave your body.
Colon cancer, on the other hand, can develop in various areas of the large intestine. Cancers that develop in the first and longest part of the large intestine are classified as colon cancer, and cancers that develop in the lower part in front of the anal canal are considered rectal cancer. Collectively, cancers of the large intestine are sometimes referred to as “colorectal cancer.”
Colorectal Cancer: Symptoms, Causes, And Treatment
Although location is a major distinction between these types of cancer, there are also major differences in the causes of these cancers and the symptoms they produce.
There is overlap in the symptoms of anal cancer and colon cancer, but more specific differences can help lead to an accurate diagnosis.
The causes and risk factors are the characteristics that differ between these two conditions. Colon cancer can be caused by a variety of genetic and lifestyle factors, but anal cancer is almost always linked to a viral infection.
Human papillomavirus (HPV) infection is thought to be the main cause of anal cancer. Although these viruses can be passed through any skin-to-skin contact, HPV-related cancers that develop in areas such as the anus, uterus, or vagina are often passed through sexual contact with an individual who has contracted HPV.
