Doctors often explain why one person develops cancer and another does not. Here in this blog, we will give you the detail information about the risk factors leading to cancer:
Tobacco: It is the main leading cause of cancer. People who use tobacco products or continuously taking environmental tobacco smoke (also called secondhand smoke) have an increased risk of cancer as tobacco products and secondhand smoke releases chemicals that damage DNA.
Alcohol: Drinking alcohol can increase your risk of cancer of the mouth, throat, esophagus, liver, and breast. The more you drink, the higher your risk. The risk of cancer increases 2 times for those who drink alcohol and use tobacco. Alcohol and tobacco may work synergistically.
Age: Advancing age is the most important risk factor for cancer overall, and for many cancer types. Median age of a cancer diagnosis is 66 years. However, cancer can occur at any age. For example, bone cancer is most frequently diagnosed among people under the age of 20 years.
Obesity: Obese people may have an increased risk of cancers of the breast (in women who have been through menopause), colon, rectum, endometrium (lining of the uterus), esophagus, kidney, pancreas and gallbladder.
Sunlight: Sunlight releases offultraviolet (UV) radiation and exposure to it causes early ageing of the skin and skin damage that can lead to skin cancer. People of all ages and skin tones should limit the amount of duration they spend in the sun, especially during the late afternoon, and avoid other sources of UV radiation.
Radiation: Radiation of certain wavelengths, called ionizing radiation, has enough energy to damage your DNA and cause cancer. Ionizing radiation includes x-rays, gamma rays, and non-ionizing forms of radiation, such as visible light and the energy from cell phones.
Hormones: Estrogen, a female sex hormone is a suspected carcinogen and has been associated with an increased risk of breast and uterine cancers. For instance, taking combined menopausal hormone therapy (estrogen plus progestin, which is a synthetic version of the female hormone progesterone) can increase the risk of breast cancer in females. Over the time, several factors may act together to develop normal cells into cancerous. Others, such as family history cannot be avoided. People can help protect themselves by avoiding the risk factors mentioned above. If you think you may be at risk for cancer or suspect any symptom of cancer, then you should definitely discuss this concern with your physician or GP soon.
