Did you know everyday choices, long-term medicines, and infections can change your cancer risk? Smoking is the single biggest avoidable factor. But hormone treatments, certain drugs, workplace exposures, chronic infections and even some supplements or online medication sources can shift your odds. This guide gives practical steps you can take and clear signs to discuss with your doctor.
Tobacco use and secondhand smoke cause the most preventable cancers. Heavy alcohol use raises risk for liver, breast and digestive cancers. Carrying excess weight and low activity increase inflammation and hormone changes that favor cancer growth. Long or high-dose hormone therapy for menopause or other conditions has been linked to higher breast or uterine cancer risk in clinical studies, so it needs careful discussion with your clinician. Specific infections — HPV, hepatitis B and C, and H. pylori — are proven causes for cervical, liver and stomach cancers; vaccines and treatment reduce those risks. Occupational hazards like asbestos, benzene, or prolonged industrial exposures also matter. Repeated high-dose medical imaging without clear need can add exposure too.
Quit smoking and avoid places with poor air quality. Limit alcohol — no safe level for some cancers, so cut back when you can. Stay active, aim for a balanced diet, and keep a healthy weight. Get vaccinated: HPV vaccine prevents cervical and other cancers, and hepatitis B vaccine protects the liver. Follow recommended screening: mammograms, Pap tests, colonoscopies, and lung screening for heavy smokers when indicated. Protect skin from sun and skip tanning beds.
Review medicines with your doctor. Some drugs bring benefits but also higher cancer odds in certain groups. For example, tibolone used in menopause has shown links to higher breast cancer incidence in trials; that doesn’t mean everyone must stop, but it does mean you should weigh risks and benefits. Targeted cancer drugs such as erlotinib are treatments, not causes, and can be lifesaving for patients with specific mutations. Overprescription and unnecessary long-term medications can complicate care — discuss whether you still need each drug, and avoid buying prescriptions from unknown online pharmacies. Our site explains how to spot safe pharmacies and why medicine quality matters.
Get checked if you notice a new lump, unexplained bleeding, persistent pain, sudden weight loss, or long-lasting fatigue. Bring a clear medication list and any family history of cancer to your visit. If many relatives had cancer or you had early-onset cancers in the family, ask about genetic testing and more intensive screening. Keep records of tests and results handy.
We offer clear articles like “Tibolone and Breast Cancer,” a case study on targeted therapy with “Erlotinib in the Treatment of Leptomeningeal Metastases,” and guides on safe medication purchases. Read those to learn specifics and prepare questions for your provider.
Small changes — quitting smoking, staying current with vaccines and screening, and reviewing medicines — add up to lower risk and better peace of mind.

A study by University of Florida researchers highlights increased cancer risks for asthma sufferers. Data from over 90,000 adult asthma patients reveal a 1.36 times higher likelihood of developing cancers like lung, blood, melanoma, kidney, and ovarian. Inhaled steroids show a protective effect. The findings underscore the need for more comprehensive research and effective asthma management strategies.
