What is the most common form of colon cancer?
There are many types of colorectal cancer, the most common of which is adenocarcinoma. Other types include carcinoid tumors, gastrointestinal stromal tumors, colorectal lymphoma.
What is an aggressive form of colon cancer?
High-grade large cell and small cell neuroendocrine tumors are aggressive. These tumors tend to grow rapidly and invade other tissues. Carcinoid tumors of the colon are considered indolent. They tend to be slower growing and less invasive than large cell and small cell neuroendocrine tumors.
What cancers are associated with colon cancer?
People who have had colon cancer can get any type of second cancer, but they have an increased risk of:
- A second colon cancer (This is different from the first cancer coming back.)
- Rectal cancer.
- Oral cavity and oropharynx.
- Stomach cancer.
- Small intestine cancer.
- Anal cancer.
- Bile duct cancer.
- Uterine cancer.
What is the difference in colon cancer and colorectal cancer?
To some, the term “colon cancer” can be used to include both colon and rectal cancers. To others, “colorectal cancer” may be applied to describe a malignancy of the colon, even if the rectum itself is not involved.
Is there more than one type of colon cancer?
There’s one main type of colorectal cancer called adenocarcinoma. While other types of tumors may develop in the colon or rectum, they’re much more rare. Adenocarcinomas of the colon and rectum make up 95 percent of all colorectal cancer cases.
What was your first colon cancer symptom?
A persistent change in your bowel habits, including diarrhea or constipation or a change in the consistency of your stool. Rectal bleeding or blood in your stool. Persistent abdominal discomfort, such as cramps, gas or pain. A feeling that your bowel doesn’t empty completely.
What part of the body does colon cancer affect?
Colorectal cancer affects the digestive system. This includes the large and small intestines. The large intestine is also called the colon. Colorectal cancer is the third leading cause of cancer-related deaths in the United States among both men and women.
Does colon cancer return after surgery?
For most people, colorectal cancer doesn’t come back, or “recur.” But in about 35\% to 40\% of people who get surgery with or without chemotherapy, the cancer may come back within 3 to 5 years of treatment. If this happens, it could be in the colon or rectum, or in another part of the body, such as the liver and lungs.
Where does colon cancer start?
Most colorectal cancers start as a growth on the inner lining of the colon or rectum. These growths are called polyps. Some types of polyps can change into cancer over time (usually many years), but not all polyps become cancer. The chance of a polyp turning into cancer depends on the type of polyp it is.
Does colon cancer cause back pain?
Cancers of the stomach, colon, and rectum can all cause lower back pain. This pain radiates from the cancer site to the lower back. A person with these cancer types may have other symptoms, such as sudden weight loss or blood in their stool.
What is the rarest form of colon cancer?
Between 90 and 95 percent of all colon cancers are adenocarcinomas. More rare forms of colon cancer include: neuroendocrine, gastrointestinal stromal tumors (GISTs), lymphoma, melanoma and leiomyosarcoma. Some of these types of cancers occur primarily in other parts of the body.
What type of cancer is most aggressive?
SCLC comprises about 10\%-15\% of lung cancers. This type of lung cancer is the most aggressive and rapidly growing of all the types.
How do you remove a tumor from the colon?
Depending on the size and extent of spread of the cancer, patients may need to undergo a surgery, removing part or all of the colon, in order to remove the tumor. For some patients, an ileostomy or colostomy may be needed, which diverts bowel content into an external bag.
Does colon cancer always cause abdominal pain?
Constipation may occur due to difficulty in stool passing the obstruction, followed by diarrhea when backed up contents are then passed. Abdominal Discomfort: Abdominal pain or cramping may occur for several reasons in those who have colon cancer. Most frequently, abdominal pains or cramps are associated with cancers on the left side of your colon.
