Doctor says i have invasive squamous cell carcinoma on my chest(sternum), what is the best way for it to be removed

Surgical Excision. There may be additional recommendations of radiation or other chemotherapy too, depending on the exact diagnosis. These are best reviewed with your surgeon. I hope this helps.

There are a variety of treatment options that have varying risks benefits and cure rates. Surgical removal has the highest cure rates in the right hands. If the cancer is large or particularly aggressive it might require Mohs surgery. Other options include a scrape and burn, freezing, or radiation. In my personal opinion surgical removal is ideal unless there is a compelling reason not to pursue surgery. 

There are a lot of factors that enter into the decision. Talk to your doctor. Surgical excision may be an excellent alternative. On the trunk Mohs surgery is generally reserved for larger skin cancers or skin cancers that have recurred following prior treatment. Radiation may also be an excellent alternative for patients who wish to avoid surgery or who have multiple serious medical problems. Speak with your doctor to discuss what is the best alternative for you. Good luck.

Most likely a surgical excision would be best, but it depends on the size of the site, as well as the margins that came back from the initial biopsy. We usually use Mohs when we need to preserve the utmost amount of skin, so in areas like the face, ears, hands, groin. Most people have more than enough area on the sternum to do a surgical excision and clear the margins, without resorting to Mohs. Your best bet is to talk to your dermatologist about what is going to be the best procedure to remove the cancer in your specific case.
