A tumor in the sigmoid colon can be benign.
Many tumors that are found in the sigmoid colon and colon are benign like polyps and other non cancerous growths.
Most colon polyps including sigmoid colon polyps are small, abnormal tissue growths which are benign.
Although some types of colon or sigmoid colon polyps such as adenomas can develop into cancer over time.
Aside from polyps, other benign tumors such as leiomyomas which are smooth muscle tumors or schwannomas or nerve sheath tumors can occur in the sigmoid colon and are often non cancerous and may not cause symptoms.
A pathologist can examine tissue samples such as through biopsies under a microscope to determine if the tumor is benign or malignant which is cancerous.
The way they remove a tumor from sigmoid colon is through surgery called a sigmoid colectomy.
A sigmoid colectomy involves removing the affected portion of the colon which can be done through open surgery or a laparoscopically, with the latter being a minimally invasive approach.
And in some cases if the tumor in the sigmoid colon is small and localized, a polypectomy or local excision during a colonoscopy may be enough.
Sigmoid colon cancer metastasis or metastasizes to the lungs and live and can also spread to the brain, distant lymph nodes and even the peritoneum and other organs.
Liver metastasis is the most frequent site for sigmoid colon cancer to spread to.
The lungs are also another common site for distant metastasis of sigmoid colon cancer and the peritoneum, which is the ling of your abdominal cavity can also be affected by metastasis of sigmoid colon cancer.
Sigmoid colon cancer can also metastasize or spread to the lymph nodes which are located far from the original tumor site.
And while less common, the sigmoid colon cancer can also spread and metastasize to the brain and potentially neurological symptoms and problems.
And also while less common, sigmoid colon cancer can spread to the bones, adrenal glands and other organs including the stomach, abdominal wall, upper urinary tract and thyroid gland.
If the sigmoid colon cancer spreads to the bones it can cause pain or bone fractures.
Stage 4 Rectosigmoid cancer means that the Rectosigmoid cancer has spread or metastasized from the rectosigmoid junction "which is where your rectum and your sigmoid colon meet", to distant organs in the body or lymph nodes in other parts of your body.
The stage of stage 4 Rectosigmoid cancer is characterized by the rectosigmoid cancer's ability to invade beyond the local area of your rectum and sigmoid colon, and it can also potentially affect organs such as the lungs and liver or even other lymph nodes in the body.
The cause of rectosigmoid cancer is not really known, although it's believed that rectosigmoid cancer is a result of a combination of genetic and lifestyle factors.
Several factors can increase a persons risk of developing rectosigmoid cancer such as age, diet, physical inactivity, family history and obesity.
Rectal cancer arises from changes in the DNA of cells in your rectum, and these changes can also be inherited or acquired during your lifetime.
And certain inherited genetic syndromes, such as Lynch syndrome and familial adenomatous polyposis also significantly increase your risk of colorectal cancer and rectosigmoid cancer.
Also eating a diet high in red meat and processed meats and a diet low in fruits and vegetables and fiber is also linked to an increased risk of rectosigmoid cancer and colorectal cancer.
The name of the surgery for rectosigmoid cancer is sigmoid colectomy with coloanal anastomosis and is also known as low anterior resection.
The rectosigmoid cancer or sigmoid colectomy with coloanal anastomosis involves the removing of the affected portion of the sigmoid colon and rectum, then the remaining colon is reconnected to the rectum or anus.
And in some cases, a temporary ileostomy may be created to allow for healing.
Rectosigmoid cancer is somewhat common but not as common as other colon cancers are.
Around 10 percent of colon cancers or colorectal cancers are rectosigmoid cancers.
Rectosigmoid junction cancer is a type of colon cancer or colorectal cancer.
Rectosigmoid junction is a cancer that occurs within your rectosigmoid junction which is the part of your large intestine that is between your sacral promontory and the lower margin of S2.
Around 10 percent of all colorectal cancers are located at the rectosigmoid junction.
Rectosigmoid cancer is cancer which occurs at the junction of your sigmoid colon and your rectum.
Colon cancer though can begin in any part of your colon, including your ascending colon, transverse colon, descending colon or sigmoid colon.
Your sigmoid colon is around a foot long and some people have the sigmoid colon removed due to cancer and because your colon is 5 feet long you can easily live without the sigmoid colon.
The sigmoid colon is sometimes removed through a procedure called a sigmoidectomy which removes the sigmoid colon and then reconnects the intestines on either side.
After your sigmoid colon is removed you may have more frequent bowel movements with loose stools, especially in the early days after the surgery.
However after around a year your bowel movements should return to normal.
The rectosigmoid junction is what marks the transition point between your sigmoid colon and your rectum and anatomically occurs at the level of your S3 vertebra.
The sigmoid colon is also part of your large intestine which stores poop before it moves to your rectum and anus.
Your sigmoid colons main function is to store poop and act as a holding chamber for poop until it is ready to be expelled.
The sigmoid colon also absorbs water, nutrients and vitamins from your poop and uses smooth muscle contractions to move poop to your rectum and anus.
The Rectosigmoid junction is on the left side and marks the point where your sigmoid colon connects to your rectum and is also considered to be part of the left side of your colon.
Your Rectosigmoid colon is on the left side of your abdomen.
The sigmoid colon is the last part of your colon and is located in the left lower quadrant of your abdomen.
Your sigmoid colon or rectosigmoid colon is between the descending colon and your rectum and near your uterus or bladder and is about 30 cm long and has an S shape to it.
Your rectum is part of your rectosigmoid colon.
The colon is also divided into the right and left sides, and the transverse colon is in between.
Your right side contains the ascending colon, cecum and hepatic flexure.
Your left side contains your splenic flexure, sigmoid colon, rectum, rectosigmoid and descending colon.
The rectosigmoid junction is located as far up as the level of your third sacral vertebra or the sacral promontory.
The adult human rectum is around 4.7 inches long and begins at your rectosigmoid junction which is the end of your sigmoid colon.
The Rectosigmoid Junction is supplied by the Sigmoidea ima artery, the inferior mesenteric artery and the marginal artery of Drummond.
The sigmoidea ima artery is the lowest sigmoid artery, which connects with the superior rectal artery and forms the distal end of the marginal artery.
The inferior mesenteric artery is what supplies the colon from your distal transverse colon to your rectosigmoid junction.
And the marginal artery of Drummond is an arterial channel which supplies your entire large intestine from your ileocecal junction to your rectosigmoid junction.
The Rectosigmoid is what serves as a storage area where stool or poop water is further recovered through absorption.
The contraction and emptying of your descending colon and rectosigmoid are stimulated by eating.
And in your rectum, your pelvic floor muscles (levator ani, puborectalis) regulate fecal retention and defecation.
The Rectosigmoid Junction is the area of your large intestine where your sigmoid colon and your rectum meet.
