Colon cancer is one of the leading causes of cancer-related deaths in modern and industrialized world. About half a million people die every year worldwide due to colon cancer.1 Colorectal cancer (CRC) (also known as colon cancer, rectal cancer, or bowel cancer) is the cancer of the large intestine (colon), the lower part of your digestive system. It arises from accumulated genetic and epigenetic alterations, which provide a basis for the analysis of stool to identify tumor-specific changes.2 Most cases of colon cancer begin as small, noncancerous (benign) clumps of cells called adenomatous polyps. Over time, some of these polyps become colon cancers. The primary reason of colon cancer is chain smoking, but there are some other reasons of colon cancer, such as family history of colon cancer, increasing age, and unbalanced diet, like diets with low consumption of fruits/vegetables and heavy consumption of meat.3 It is the development of cancer in the colon or rectum (parts of the large intestine). It is due to the abnormal growth of cells that have the ability to invade or spread to other parts of the body.4

Most rectal carcinomas are annular or polypoid tumours that invade the wall of the rectum. Tumour invasion occurs through the layers of the rectal wall, i.e. mucosal layer, submucosa and muscularis propria. Tumours that have invaded through the full thickness of the rectal wall may then extend into the surrounding mesorectal fat layer. Tumour may then invade adjacent structures such as bladder or seminal vesicles, or may perforate into the peritoneal cavity. Rectal carcinoma may also spread to regional lymph nodes in the pelvis or metastasize to distant sites, such as abdominal lymph nodes or liver.

Colorectal Cancers – This term refers to cancers of the colon and the rectum, also called bowel cancer. It is the development of cancer from the colon or rectum (parts of the large intestine) and usually requires surgery for treatment. This cancer is curable as well, although it can recur after surgery, often resulting in fatalities. However, early detection can reduce the need for surgery, thereby helping the patient heal fully. Hence, we expect our solution to be capable of working in favor of this goal.
Effect of bladder and rectal loads on the vaginal canal and levator ani in varying pelvic floor conditions

Arnab Chanda, Vinu Unnikrishnan
The effect of bladder and rectal loads were studied for the pelvic floor muscle (levator ani) in normal pelvic floor conditions. With increased bladder loading and no rectal loading, the stress concentration and displacements on the levator ani (Figure 13) were found to increase with maximum displacement going up from 0.22 mm to 0.49 mm. The maximum displacement concentration zone was observed to be close to the posterior attachment of the levator ani at the coccyx. This finding indicated that in severe bladder loading conditions due to prolapse, there might be a high chance of pelvic floor failure initiating at the coccyx region. Also, a high stress and displacement region observed close to the anterior puborectalis section of the levator ani (which supports the urethra, vaginal and rectal hiatus) may indicate high-induced obstructions at the bladder, vaginal and rectal hiatus regions leading to pressure and hence difficulty emptying the bladder and SUI [7].
