We know a lot about how ecigs promote cancer metastasis

E-cig advocates and regulators including the FDA continue to assume that e-cigarettes pose much lower cancer risks than cigarettes because e-cigarettes deliver much lower levels of cancer-causing chemicals (carcinogens) produced by burning tobacco.

Evidence that e-cigarettes promote breast cancer

E-cigarette advocates and pro-tobacco forces generally love to point on that nicotine does not cause cancer. While they are correct that nicotine does not cause cancer, i.e., does not lead to cancer initiation, the fact is that once someone has cancer, nicotine makes it worse.
