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.
5. Previous Cancer Treatments
- Cancer treatments like chemotherapy and radiotherapy can slightly increase the risk of developing another cancer.
- This risk is rare and should not deter necessary treatment.
- Follow up with doctors for post-treatment care and rehabilitation.
