A myxoma is a rare benign tumor of the heart. Myxomata are the most common primary cardiac tumor in adults, and are most commonly found within the left atrium near the valve of the fossa ovalis. Myxoma may also develop in the other heart chambers. [1] The tumor is derived from multipotent mesenchymal cells. [1]
The most common type of primary tumors in adults—when they do happen—are myxomas. Myxomas are benign tumors that arise from the mesenchymal connective tissue inside the heart, as opposed to the actual myocytes, or the heart cells, since as an adult, the heart’s fully developed and its cells, or myocytes, are permanent and don’t proliferate.
In most cases, patients with heart metastases have advanced tumour disease, with the heart being only one of the many places involved in the generalised tumour spread. At that stage of the disease, the patients will likely have already undergone extensive chemotherapy, radiation therapy or surgical procedures. Cardiac treatment is usually ...
The incidence of primary cardiac tumors has been found to be approximately 0.02%. [1] This is in contrast to secondary tumors of the heart, which are typically either metastatic from another part of the body, or infiltrate the heart via direct extension from the surrounding tissues. Metastatic tumors to the heart are about 20 times more common ...
It has been statistically demonstrated that screening programs are effective in reducing the number of deaths caused by colon cancer due to adenomatous polyps. The risk of complications associated with colonoscopies is approximately 0.35 percent, compared to a lifetime risk of developing colon cancer of around 6 percent. [23]

The change allows numerous cells of the intestinal wall to develop into potentially cancerous polyps when they would usually reach the end of their life; inevitably one or more will eventually progress and give rise to cancer (7% risk by age 21, rising to 87% by age 45 and 93% by age 50). These gene changes do not trigger cancer, but rather ...
Social-media-savvy Will Smith recorded himself preparing to undergo a colonoscopy and its aftermath for a vlog, and in the process discovered he had a precancerous polyp that had to be removed.
