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.
Myxoma is a rare, benign stromal tumor of mesenchymal origin often confused with other conjunctival stromal tumors. Conjunctival myxomas are thought to originate in Tenon's capsule and can masquerade as conjunctival lymphoma, lymphangioma, ocular surface squamous neoplasia (OSSN), or amelanotic melanoma.
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]

Fibrosis in the heart is often hard to detect because fibromas, scar tissue or small tumors formed in one cell line, are often formed. [3] Because they are so small, they can be hard to detect by methods such as magnetic resonance imaging. [1] A cell line is a path of fibrosis that follow only a line of cells.
