Frequently Asked Questions

General questions

What is cancer, and how does it start?

Cancer is a disease where cells in the body grow uncontrollably. Normally, cells grow, divide, and die when needed. In cancer, this process goes wrong — cells don’t stop growing and may form a lump (tumour) or spread to other parts of the body. It can start anywhere and often develops quietly at first. Not all tumours are cancerous; some are benign and don’t spread. Early detection improves treatment success.

Can cancer be cured?

Many cancers can be cured, especially if found early. Some types respond very well to treatment and never return. Others may be managed as chronic conditions, like diabetes. Cure depends on the type, stage, and how early it’s treated. Modern treatments are improving survival and quality of life every year. The key is timely diagnosis and following through with care plans.

What are the common signs of cancer?

Cancer symptoms can vary, but common warning signs include:

  • Unexplained weight loss
  • Ongoing fatigue
  • Lumps or swelling
  • Changes in skin or moles
  • Unusual bleeding
  • Persistent cough or difficulty swallowing
    If a symptom doesn’t go away, speak to your doctor. Early testing is the best way to catch problems before they grow.

Does early detection really make a difference?

Absolutely. Finding cancer early often means simpler treatment, fewer side effects, and a higher chance of recovery. Early-stage cancers are usually smaller and haven’t spread, making them easier to remove or treat. Screening tests and regular check-ups help detect cancers before symptoms appear. Early action can save lives.

What causes cancer?

Cancer is caused by changes in a cell’s DNA. These changes may happen naturally or due to factors like smoking, poor diet, long-term infections, radiation, or chemical exposure. Age, lifestyle, family history, and environmental factors all play a role. Often, there’s no single cause, but reducing risks helps protect your health.

Is cancer always inherited from the family?

Not always. Only about 5–10% of cancers are strongly linked to inherited genes. Most cancers occur due to lifestyle, age, and environmental factors. However, if several family members had the same type of cancer, especially at a young age, it’s worth discussing with your doctor. Genetic testing is available for high-risk families.

How does chemotherapy work?

Chemotherapy uses special medicines to kill cancer cells or stop them from growing. It can be given as pills, injections, or through a drip. It may be used alone or with surgery or radiation. While it can affect healthy cells too (causing side effects like tiredness or hair loss), doctors carefully plan treatment to get the best results with the least harm.

Is radiation therapy safe?

Yes, when delivered by trained professionals using modern machines, radiation therapy is very safe. It uses high-energy rays to destroy cancer cells with precision. The equipment and planning ensure the radiation targets the tumour, not healthy tissues. Mild side effects may occur but are usually temporary and manageable.

Can cancer spread to other parts of the body?

Yes, cancer can spread — this is called metastasis. Some cancers stay local, while others may travel through the blood or lymph system to other organs. This is why early diagnosis is so important. Treatments are available to manage or stop the spread, depending on the type and stage.

What is the difference between benign and malignant tumours?

Benign tumours are non-cancerous. They grow slowly and don’t spread to other parts of the body. Malignant tumours are cancerous — they can invade nearby tissues and spread. Only malignant tumours are considered cancer, but even benign tumours may need removal if they cause problems.

Are cancer treatments painful?

Most treatments are not painful, but some may cause side effects that can be uncomfortable. Doctors take steps to minimize pain and manage symptoms during and after treatment. Supportive care, medication, and counselling can help you feel more comfortable and supported throughout the process.

Can healthy people get cancer screenings?

Yes. Screening is for people without symptoms and helps find cancer early. Tests like mammograms (for breast cancer), Pap smears (for cervical cancer), and colonoscopies (for colon cancer) are common. If you’re over 40 or have a family history, speak to your doctor about what screenings are appropriate for you.

Does cancer always mean death?

Not at all. Thanks to modern medicine, many people survive cancer and live full, comfortable lives. Survival depends on the type, stage, and how quickly treatment starts. Many cancers are curable, and others can be managed long-term. Early detection, quality care, and support make a huge difference.

Can lifestyle changes help prevent cancer?

Yes. Healthy habits can lower your risk. These include:

  • Eating a balanced diet rich in fruits and vegetables
  • Avoiding tobacco and alcohol
  • Staying active
  • Maintaining a healthy weight
  • Protecting your skin from the sun
  • Getting vaccinated (e.g. HPV, Hepatitis B)

While no method guarantees prevention, these choices improve your overall health and reduce risk.

Is secondhand smoke dangerous for cancer?

Yes, secondhand smoke increases your risk of lung cancer and other diseases. Even if you don’t smoke, breathing in smoke from others can be harmful, especially over long periods. Protect yourself and your family by avoiding smoky environments and encouraging smoke-free homes and workplaces.

Can children get cancer?

Yes, but it’s rare. Childhood cancers are different from adult cancers and often respond well to treatment. Common types include leukemia, brain tumours, and lymphomas. If your child has unusual symptoms that don’t go away — like unexplained fever, fatigue, or swelling — talk to a doctor.

What should I do if I suspect I have cancer?

See a medical doctor as soon as possible. Don’t panic — many symptoms have non-cancer causes. Your doctor will examine you, recommend tests, and guide the next steps. Early action gives you more options and better outcomes. Waiting won’t help; getting answers will.

How can I support a loved one with cancer?

Listen, be present, and offer practical help like transport or meals. Avoid offering unsolicited advice — just being there means a lot. Encourage them to follow medical advice, attend appointments, and rest. Emotional support can be just as important as medical care.

Can cancer come back after treatment?

Yes, some cancers can return after treatment — this is called recurrence. The risk depends on the type and stage of cancer. Regular follow-up care helps detect any changes early. Staying healthy and keeping up with medical advice improves long-term outcomes.
