乳癌發生在左胸比右胸更常見。

左胸比右胸有5 - 10%的更多可能形成癌變。人的身體左側也有10%的機率更容易患上黑色素瘤(一種皮膚癌)。沒人確切地知道這是為什麽。 

Breast cancer is more common on the left side than on the right.

The left breast is 5-10% more likely to become cancerous than the right one. There is also a 10% chance of getting melanoma (a type of skin cancer) in the left side of the body. The reasons for these phenomena have not been exactly known.
