Cancer is a complex disease with various contributing factors, and there is no single precise cause. Here are some known factors that can increase the risk of cancer:
1. Genetics
Inherited genetic mutations can increase the risk of certain cancers, like breast and colorectal.
Genetic testing may be considered for those with a strong family history of cancer.
2. Smoking
Smoking exposes you to over 69 cancer-causing agents.
Increases the risk of lung, oral, stomach, kidney, and bladder cancers.
Even light smoking is harmful.
Second-hand smoke is dangerous for non-smokers.
3. Sun and UV Exposure
Overexposure to UV radiation from the sun or tanning beds can lead to skin cancer.
Fair-skinned individuals are more susceptible.
Use sunscreen (SPF 15 or higher), seek shade, wear protective clothing, and use UV protection.
4. Radiation Exposure
Natural and man-made radiation exposure can potentially cause cancer.
Medical imaging, like X-rays and CT scans, involve radiation.
Safety measures, like lead aprons, can reduce exposure risks.
