D16 on Vancouver Craigslist

Speaking of D16RRs, I was behind one in our club's group ride today. It certainly is a unique sounding (and smelling) bike.

No mention of heart cancer on the American Cancer Society website...  I did a search

A negative result is not proof.  mstevens is an MD and knows his stuff.

From the Mayo Clinic website:

http://www.mayoclinic.com/health/heart-cancer/AN01288

Heart cancer is extremely rare. Although heart tumors do occur, the vast majority are noncancerous (benign). A 20-year review of 12,487 consecutive autopsies in Hong Kong identified only seven cases of cardiac tumor â€" an incidence of less than 0.1 percent â€" most of which were benign.

Cancerous (malignant) tumors of the heart are most often sarcomas, a type of cancer that originates in the soft tissues of the body. Occasionally, cancer can spread to the heart, such as from lymphomas that originate in the structures of the chest near the heart. Other cancers that can spread to the heart include melanomas and sarcomas.

Cancer can affect the heart in other ways, such as by causing damage to the heart valves (marantic endocarditis) or stiffening of the heart muscle (cardiac fibrosis). Cancer treatments can also affect the heart. Certain chemotherapy drugs â€" such as anthracyclines, high-dose cyclophosphamide (Cytoxan), 5-FU, taxanes, trastuzumab (Herceptin) and IL-2 â€" can damage the heart. Radiation therapy directed at or near the heart can cause damage to the heart muscle and increase the risk of coronary artery disease later in life.

even benign tumors in/around the heart are no joke. Tumors can grow pretty much anywhere.

You're not looking in the right place, then. When I was in medical school I saw two people die of primary cardiac malignancies.

There are most certainly cardiac sarcomas, which are primary heart malignancies. Metastases can also occur to the heart from primary sites elsewhere.
