No one wants to hear their doctor say the dreaded C-word. Cancer brings feelings of fear, worry and anger. However, many cancer treatments can improve your chances of survival, and around half of cancer patients go on to live ten years or more afterwards.

While these treatments are great for improving your chances of survival, they do come with side effects. It’s not guaranteed that everyone will experience these effects, and it shouldn’t put off patients, but it’s important to understand what’s in store for your body.

To help prepare you, here are four well-known cancer treatments and their common side effects, with helpful tips on how to cope.


This is probably the most well-known cancer treatment due to its versatility. Chemotherapy is circulated through the bloodstream, reaching every part of the body, making it the go-to therapy for several cancer types.

There are several ways you can receive chemotherapy. Sometimes it’s given as a tablet or capsule, by infusion through the veins, and sometimes even an injection or cream. The way you receive this treatment will depend on your circumstances.

You may experience some of these side effects or many. It’s important to remember that these side effects are only temporary during treatment.

Chemotherapy tips

  • Rest often
  • Drink plenty of water
  • Ask for nausea medication
  • Buy a wig
