In short
- Side effects differ by medicine and by person. Your oncologist can tell you what to expect from yours.
- Asking before treatment starts means you can prepare.
- Bring your products to the appointment so your team knows what you are using.
Before treatment starts
- Which skin, hand or foot side effects are most likely with my treatment?
- When do they usually start, and how long do they last?
- Is there anything I should start doing from Day 1 to protect my skin?
- Are there products or ingredients I should avoid?
- Who do I call if I have a problem between appointments, and at what number?
If you are having radiotherapy
- How should I wash and care for the treated area?
- How long before each session should I stop applying cream?
- Can I use deodorant, and which type?
- What should I do if the skin peels or breaks?
- How long should I continue skin care after my last session?
If you are having chemotherapy
- Can my medicines cause tingling or numbness in my hands and feet?
- Can they cause redness or soreness on my palms and soles?
- At what point should I report these symptoms?
- If symptoms appear, how might my treatment change?
- Should I avoid cold, or cooling products?
If you are having targeted therapy or immunotherapy
- Is a skin rash likely, and what should I do if one appears?
- Do I need sun protection, and which kind?
- Are there skin changes I should report straight away?
About the products you use
- Is this cleanser, cream or roll-on suitable for me?
- In what order should I apply it with anything you have prescribed?
- Is there anything in the ingredient list you would prefer me to avoid?
Tips for the appointment
- Write your questions down and take them with you.
- Bring someone with you if you can. Two people remember more than one.
- Take photos of skin changes as they happen, with dates.
- Ask for anything you do not understand to be explained again. It is a normal request.
Do not wait for your next appointment if
- You have a fever
- Skin is blistering, open or looks infected
- You have a widespread rash
- Pain or numbness is stopping you walking or using your hands
Call the number your team gave you, or go to the nearest hospital in an emergency.
