The prime cause of cancer is unknown, but studies associate constant exposure to certain chemical components with an increased risk of developing the condition. Statistics indicate that cancer is the second leading cause of death in the country, next to heart disease. Some risk factors are more prominent, like inherited flawed genes, radiation exposure, and unhealthy lifestyle habits. But here are some unsuspecting things surrounding us that may add to the problem . Hair straightener Chemical hair straighteners and relaxers contain harmful chemicals like parabens, bisphenol A, metals, or formaldehyde. According to experts, these chemicals may increase the risk of developing uterine cancer. These chemicals get more easily absorbed into the scalp.

Talcum powder Talc, a mineral mainly used in making talcum powder, is mined from the earth. In its natural form, the substance contains asbestos, a carcinogen strongly linked to different cancers. Talc miners, for instance, who are exposed to it for a long time may be at risk of lung cancer. Alternatively, women using talc near the private parts may be at risk of developing ovarian cancer. Asbestos-free talc can be a relatively safer option.
