Question 1

What does preventive oncology focus on?

Accepted Answer

Preventive oncology focuses on reducing cancer risk and detecting cancer at its earliest, most treatable stage through risk assessment, lifestyle counselling, and structured cancer screening programmes, such as mammography for breast cancer, Pap smears for cervical cancer, colonoscopy for colorectal cancer, and low-dose CT scans for lung cancer in high-risk individuals. This proactive approach aims to catch cancer before symptoms develop, when treatment is typically most effective.

Question 2

Which cancer screening tests are recommended and at what age?

Accepted Answer

Common recommendations include mammograms starting around age 40-45 for average-risk women, Pap smears starting around age 21 and continuing at intervals through the 60s, colorectal cancer screening starting around age 45-50, and lung cancer screening for long-term heavy smokers typically starting around age 50. Exact recommendations vary by guideline and individual risk factors, so a preventive oncology consultation can help determine the right screening schedule tailored to your personal and family history.

Question 3

Who is considered high risk and may need earlier or more frequent cancer screening?

Accepted Answer

Individuals with a strong family history of cancer, known genetic mutations like BRCA1/2, a personal history of certain precancerous conditions, or specific lifestyle risk factors such as long-term heavy smoking, may be considered high risk and benefit from earlier or more frequent screening than the general population. A preventive oncology or genetic counselling consultation can help assess your specific risk profile and recommend an appropriately tailored screening schedule.

Question 4

What lifestyle changes meaningfully reduce cancer risk?

Accepted Answer

The most impactful, evidence-based changes include not smoking or quitting if you do, limiting alcohol intake, maintaining a healthy body weight, staying physically active, eating a diet rich in fruits, vegetables and whole grains while limiting processed and red meat, and protecting skin from excessive sun exposure. Getting recommended vaccinations, such as HPV vaccine, and completing recommended cancer screenings also play an important preventive role. While no lifestyle change guarantees cancer prevention, these measures meaningfully reduce risk across multiple cancer types.

Question 5

What happens if a screening test comes back abnormal?

Accepted Answer

An abnormal screening result doesn't necessarily mean you have cancer; many abnormal findings turn out to be benign once further evaluated. Your doctor will typically recommend additional, more detailed testing, such as diagnostic imaging or a biopsy, to clarify the finding. Try not to panic while waiting for follow-up results, but do follow through with recommended next steps promptly, since timely follow-up is what allows preventive screening to be effective at catching problems early.
