Blood clots and cancer – what’s the link?

If you currently have cancer or are receiving treatment for cancer, it’s important to understand the connection  between cancer and the risk of developing a blood clot, which can include:

  • deep vein thrombosis (DVT) - a blood clot that forms in a deep vein (e.g. in the legs, arms or abdomen)1
  • pulmonary embolism (PE) - when a blood clot breaks away from a vein and travels to the blood vessels of the lungs2


To help you understand your risk of developing blood clots with cancer or how to manage it, read the guide below to prepare yourself for a discussion with your doctor. 

Before your doctor’s appointment
  • Think about what you want to get out of your appointment - this will help you have a more productive conversation with your doctor

  • Make a list of specific questions you have about your condition - to help you remember the information you need

  • Bring a notepad or your phone on the day to jot down notes or important reminders during your consultation

During your doctor’s appointment

Take your time

  • Stay relaxed so that you remember the points you wanted to discuss

  • Refer to your notes to keep the conversation on track


Be honest

  • Don’t wait to be asked about a symptom or concern - tell your doctor or nurse what is on your mind

  • Give as much information as possible by referring to your list of prepared questions 


Be open

  • Tell your doctor or nurse how you are feeling and your overall wellbeing

  • Be specific about what is affecting you


Keep a record

  • Make notes on what you wanted to raise - particularly if you do not have time to discuss everything during the consultation

  • If you have someone with you at the appointment, ask them to write notes for you

  • Keep a record of any relevant documents - in case you need to refer to them later


Agree on next steps

  • Set up a plan of action with your doctor

  • Confirm your next appointment date - be clear on what you need to do before then

  • Follow-up on any questions you have, or anything you do not understand

  • It is important to be completely clear about your treatment or care plan

After your appointment

Reflect on key points

  • Re-read the notes made during your appointment – did they make sense?

  • Did you get answers to all your questions? Check if there’s anything missing


Update your family, friends or carer

  • It might be useful to share the outcomes of your appointment with your family, friends or carer

  • This keeps your loved ones informed about your treatment or care plan, so they are able to support you as needed


Follow-up appointments

  • Think about what went well and what you would like to do differently at future appointments

  • What questions would you have liked to ask? 

  • Prepare a list of unanswered or new questions to raise at your next appointment

Questions to consider asking your doctor
  • What type of blood clot do I have and where is it located? 
  • Why does having cancer increase the chance of developing a blood clot?
  • Are certain cancers more likely to result in a blood clot?
  • How can I prevent blood clots forming during cancer treatment?
  • How will having a blood clot affect my cancer treatment? 
  • What side effects can I expect from my treatment? 
  • Can I still exercise? 
  • Can I take other medications?
  • What other sources of support are available to me?
