Quick read
Key points
- 1
Targeted therapy is a type of cancer treatment that works by targeting specific genes, proteins, or the tissue environment that contribute to cancer growth, rather than affecting all rapidly dividing cells like traditional chemotherapy. This can make it more precise, with a different side-effect profile.

What is Targeted therapy?
Targeted therapy is a type of cancer treatment that works by targeting specific genes, proteins, or the tissue environment that contribute to cancer growth, rather than affecting all rapidly dividing cells like traditional chemotherapy. This can make it more precise, with a different side-effect profile.
It's used for certain cancers with specific genetic or molecular features, identified through testing of a tumour sample. It may be used alone or alongside other treatments such as chemotherapy, surgery, or radiotherapy.

When to see a doctor
- 1You've been offered targeted therapy and have questions about what it involves
- 2You're experiencing side effects during treatment
- 3You'd like to understand whether your cancer has the specific markers needed for targeted therapy
- 4You have concerns about how targeted therapy fits with your other treatments
- 5You need advice about managing symptoms between treatment cycles

Practical steps
Take these self-care steps
These measures can help ease symptoms, support recovery, and reduce the chance of things worsening — but they don't replace medical advice if symptoms are severe or persistent.
- 1Understand your specific treatment plan.Targeted therapies vary widely, so ask your oncology team to explain exactly how yours works and what to expect.
- 2Report side effects promptly.Because targeted therapies can cause different side effects to traditional chemotherapy, such as skin or blood pressure changes, prompt reporting allows quick management.
- 3Take medication exactly as prescribed.Many targeted therapies are taken as tablets at home, so following dosing instructions precisely is important for effectiveness.
- 4Attend all monitoring appointments.Regular blood tests and scans help track how well the treatment is working and catch any side effects early.
- 5Ask about interactions.Some targeted therapies interact with other medications or foods, so check with your team before starting anything new.

BarnMD Bottom Line
Targeted therapy offers a more precise approach for certain cancers, and understanding your specific treatment and its side effects helps you manage it confidently.
Targeted therapies are only suitable for cancers with specific genetic markers, so testing your tumour is an essential first step.
