Usually, when we announce a celebrity is raising awareness for cancer, it is the result of a news release that the celebrity has joined a cancer foundation in an effort to lend a higher visibility to the campaign.

In the case of actress Julia Roberts, it appears simply having your photo taken is enough to raise awareness about cancer. At a Hollywood tribute to George Clooney, photographers noticed a mole on her right breast which led to a cancer expert urging Roberts to get it checked out. A dermatologist is suggesting that it looks like a scar resulting from the removal of a mole, according to the movie and entertainment reporting of the incident.

Do you think celebrities ever get fish-bowl claustrophobia from such intense scrutiny and unsolicited advice into their private life? Roberts strikes me as an intelligent woman, and I would wager she is aware of her mysterious mole and has sought medical attention for it.

However unintended as a service to public health information, this latest celebrity gossip about Roberts' right breast does create conversation into what might qualify as a suspicious-looking mole likely to warrant medical attention.

The warning signs of a mole that can cause cancer concern are:



Asymmetry -- One side of the mole does not match the other side of the mole and appears uneven.

Border -- The edge of the mole has a ragged or irregular border.

Color -- The color of the mole is uneven and varies in shade.

Diameter -- A mole bigger than a pencil eraser.

There are three main types of skin cancer: basal cell carcinoma, squamous cell carcinoma and malignant melanoma. Basal cell carcinoma and squamous cell carcinoma are the most common and malignant melanoma can be the most deadly if not caught in its earliest stage. This year in the US, more than one million people will be diagnosed with non-melanoma skin cancer, and 62,190 will be diagnosed with melanoma, according to the American Cancer Society.
