Overview
What is Chemotherapy?
- Chemotherapy (often called “chemo”) is a type of treatment that uses medicines to destroy cancer cells or stop them from growing.
- It is used for many types of cancer and sometimes for other conditions involving abnormal cells.
- Chemotherapy may be given alone or combined with other treatments (like surgery, radiotherapy, or immunotherapy).
Who is affected?
- People diagnosed with cancer may receive chemotherapy as part of their treatment.
- Some non-cancer conditions (like certain blood disorders) are also treated with chemo.
- People of all ages, backgrounds, and both genders may need chemotherapy.
Causes and Risk Factors
Why does it happen?
- Chemotherapy is used to treat diseases that involve abnormal cell growth, especially cancer.
- The reason for needing chemotherapy depends on your specific diagnosis.
Are certain people more at risk?
- People with a cancer diagnosis may require chemotherapy based on the type, stage, and aggressiveness of their cancer.
- Your doctor will explain why chemo is recommended for your situation.
Symptoms
What are the common signs and symptoms (side effects) of chemotherapy?
- Tiredness or fatigue
- Hair loss
- Nausea or vomiting
- Loss of appetite or taste changes
- Mouth sores
- Lowered blood counts (which can increase risk of infection, bruising, or bleeding)
- Skin or nail changes
- Some people have very mild side effects, while others may experience more severe reactions.
Diagnosis
How is it diagnosed?
- Chemotherapy is not a disease but a treatment, so it’s prescribed after diagnosis of cancer or certain blood disorders.
What tests are commonly done?
- Blood tests to check your blood counts, kidney, and liver function
- Imaging scans (CT, MRI, X-ray) to track how cancer is responding
- Sometimes, biopsies or bone marrow tests
Treatment Options
What are the treatment choices?
- Chemotherapy medicines can be given in different ways: by mouth (tablet or capsule), by injection, or through a drip (IV).
- Treatment cycles: Chemo is often given in cycles—periods of treatment followed by rest.
- Sometimes chemotherapy is combined with other treatments, like surgery or targeted therapy.
Are there any advanced or investigational therapies?
- New drugs and combinations are always being studied in clinical trials.
- Some people may be eligible for advanced treatments like immunotherapy or targeted therapies, based on their cancer type.
Dietary Advice
What to eat and what to avoid
- Eat a balanced diet: Plenty of fruits, vegetables, whole grains, lean protein, and healthy fats.
- Small, frequent meals can help if you have poor appetite.
- Stay hydrated—drink water regularly.
- Avoid raw or undercooked meats, fish, or eggs if your immunity is low.
- Limit sugary foods and alcohol.
Nutrition tips to support treatment or symptom control
- Try bland foods (like crackers or toast) if you feel nauseous.
- Cold foods may be easier to tolerate if you have mouth sores.
- Soft foods can help if swallowing is difficult.
Common supplements (if applicable) and when to discuss with your doctor
- Don’t start vitamins or supplements without checking with your doctor, as some can interact with chemotherapy.
- Ask about supplements if your blood counts are low or you have trouble eating enough.
Food safety or drug-food interactions
- Wash fruits and vegetables thoroughly.
- Be careful with grapefruit and some juices—they can affect how certain chemo drugs work. Always ask your doctor or pharmacist about interactions.
Chemotherapy, Fertility, and Pregnancy
Advice on Avoiding Pregnancy
- Chemotherapy medicines can seriously harm an unborn baby, so it is very important not to become pregnant or father a child during treatment.
- Both women and men should use effective contraception during chemotherapy and for some months after treatment ends (your doctor will advise how long).
- This applies even if your periods stop during treatment, as fertility may still be possible.
- Use barrier methods (like condoms) and/or other forms of birth control as recommended by your doctor.
- Do not try to become pregnant or father a child until your healthcare team tells you it is safe.
Risks of Infertility
- Chemotherapy can cause temporary or permanent infertility in both women and men.
- The risk depends on your age, the drugs used, and the dose.
- For women, chemotherapy may cause your periods to become irregular or stop completely (sometimes permanently, especially as you get older).
- For men, chemotherapy can reduce sperm count or cause sperm production to stop.
What can you do?
- Before starting treatment, talk to your doctor about your plans for having children in the future.
- Options like egg, sperm, or embryo freezing (fertility preservation) may be available before you start chemotherapy.
- If you have concerns or want more information, ask to see a fertility specialist.
Living with the Condition
Managing daily activities
- Rest when you need to, but try gentle activity like walking to keep up your strength.
- Plan important activities for times when you feel your best.
Exercise, lifestyle, and emotional well-being
- Light exercise, such as stretching or yoga, may help with fatigue and mood.
- It’s normal to feel anxious or low—talk with your healthcare team about counseling or support groups.
Sexual Health, Fertility, and Family Planning
- If you are sexually active, always use reliable contraception during and after chemotherapy as recommended by your doctor.
- Talk openly with your doctor or nurse about any questions regarding fertility, sexual health, or family planning.
Tips for long-term monitoring and follow-up
- Regular blood tests and check-ups are needed.
- Report any new or worsening symptoms to your doctor promptly.
- Keep a diary of your side effects and questions to discuss at your visits.
