RedFlags
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.
