The Next 25 Years Begin Now

We welcome you to join us as we build our bold vision for a world without sarcoma cancer.

Red Flags

At Rein In Sarcoma, the Red Flags of Sarcoma Program is driven by one purpose: saving lives through early detection. By raising awareness of the warning signs, we empower patients, caregivers, and medical professionals to recognize sarcoma sooner — when treatment can be most effective. Every conversation, every shared resource, and every trained eye brings us closer to catching sarcoma before it advances.


Together, we shine a light on the red flags that matter. Whether you spread the word, educate your community, or support our outreach, you are part of a movement that turns knowledge into hope and awareness into action.

Red Flags of Sarcoma Program

Knowledge is power. The Red Flags of Sarcoma Campaign educates the public on the symptoms of sarcoma, with the goal of promoting early detection and ultimately saving lives. 

  • I had pain in the top of my foot that would come and go. The general doctor thought it was gout. An MRI revealed it was a malignant tumor. This was also the first time I heard about Ewings Sarcoma. We were lucky to catch the tumor in a timely manner.

Lumps, bumps and bruises: the red flags of sarcoma

Not all lumps, bumps and bruises are cancerous. However, sarcoma is best treated if diagnosed early. Be vigilant, seek help and ask questions.

Be alert to:

  • that is deep, new or getting larger
  • that is 1-2 inches large (no larger than a golf ball)
  • anywhere in your body
  • Any lump or bump:
    • that is deep, new or getting larger
    • that is 1-2 inches large (no larger than a golf ball)
    • anywhere in your body
    • whether or not it hurts (not all sarcomas are painful)
  • Pain
    • that is not explained by injury or excessive activity
    • that occurs at night
    • that persists when resting the sore area
    • that lasts more than one month

Be sure to seek medical attention if you or your child experiences:

  • More pain than is expected from an incident.
  • Pain that doesn’t go away despite treatment.
  • Any areas on the body that should be the same on both sides, but are not.
  • Discomfort when moving an arm or leg.
  • A lump or bump that is growing, and may or may not be painful.
