I’ve Just Been Diagnosed with Leiomyosarcoma. What Happens Next?

A diagnosis of Leiomyosarcoma can feel overwhelming. Learn what usually happens next, who will be involved in your care and where to find trusted information and support.

Being told you have Leiomyosarcoma (LMS) can be frightening. You may never have heard of it before and suddenly find yourself faced with unfamiliar words, new appointments and lots of unanswered questions.

If you’re feeling overwhelmed, you’re not alone. Many people describe the days and weeks following diagnosis as a blur. It’s completely normal to feel shocked, anxious or uncertain about what comes next.

While everyone’s experience is different, there are some common steps that many people go through after a diagnosis.

Understanding your diagnosis

Leiomyosarcoma is a rare type of soft tissue sarcoma that develops in smooth muscle tissue. Because it is uncommon, your medical team may arrange further tests or review your results before discussing the most appropriate treatment options.

You may also be referred to a specialist sarcoma centre where doctors and healthcare professionals have experience in diagnosing and treating rare sarcomas like LMS.

More tests may be needed

Although you’ve received a diagnosis, your doctors may still need more information before recommending treatment.

This could include scans, blood tests or reviewing tissue samples to better understand your tumour, where it is located and whether it has spread.

Waiting for results can be one of the most difficult parts of the process, but these tests help your medical team plan the treatment that is most appropriate for you.

Your case will usually be discussed by a specialist team

Many people diagnosed with Leiomyosarcoma will have their case reviewed by a multidisciplinary team, often called an MDT.

This brings together specialists from different areas of healthcare, such as surgeons, oncologists, radiologists and pathologists, who work together to recommend the best treatment plan for your individual circumstances.

Although you may not meet everyone involved, their combined expertise helps ensure your care is carefully considered.

Don’t be afraid to ask questions

It is easy to leave an appointment only to think of questions afterwards.

Writing questions down before appointments or taking someone with you can really help.

Remember, it is okay to ask for medical terms to be explained, to request information to be repeated or to ask why a particular treatment has been recommended.

There are no silly questions when it comes to understanding your own care.

Looking after yourself emotionally

Receiving a cancer diagnosis affects everyone differently.

Some people want lots of information immediately. Others need time to process what they have been told before they feel ready to ask questions.

Whatever you’re feeling is valid.

Try not to feel pressured to have all the answers straight away. Taking things one appointment, one conversation and one day at a time is often enough.

You are not alone

One of the challenges of a rare cancer is that it can feel isolating. Many people diagnosed with Leiomyosarcoma have never met anyone else with the condition.

At Leiomyosarcoma Research UK, we understand that feeling.

Our charity was founded by people whose lives have been directly affected by Leiomyosarcoma. We are committed to improving awareness, supporting research and helping patients and families access reliable information about this rare cancer.

Although the road ahead may feel uncertain today, there are healthcare professionals, researchers, charities and a growing community of people working together to improve the future for everyone affected by LMS.
