Targeted therapies


Targeted therapy is a type of treatment that may be used for cancer.

51ɫAPP out what it is, what side effects to expect and how Maggie's can help.


What are targeted therapies?

The aim of targeted therapy is to kill or disrupt cancer cells, but leave normal cells unaffected.

This is different from chemotherapy, which is a type of systemic anti-cancer therapy (SACT) that affects all cells.

Targeted therapies work in different ways, including: 

  • seeking and destroying cancer cells
  • interfering with the growth or the blood supply of cancer cells
  • encouraging your immune system to attack the cancer cells 
  • acting as transport to guide other treatments like chemotherapy directly to the cancer cells

Some targeted therapies are sometimes known as biological therapies.


Side effects

Side effects for targeted therapy can vary. Your doctor or specialist nurse will talk through which ones you are likely to get depending on what therapy you're having.

It's important to let your healthcare team know about any side effects you experience so they can be treated quickly.

The most common is skin changes, including:

  • very sensitive skin
  • itching
  • a rash
  • redness

    Your healthcare team should give you a leaflet about the specific type of targeted therapy you're having.

    You can bring your leaflet to your nearest Maggie's centre at any time, and our team will talk you through what side effects you might experience. They can also support you with ways to manage these side effects.
