RMS can refer to two distinct diseases:
1. Rhabdomyosarcoma (RMS): A Rare Cancer
Rhabdomyosarcoma (RMS) is a rare and aggressive type of cancer that develops in the soft tissues, most commonly in the skeletal muscle. It's the most prevalent soft tissue cancer affecting children and teens. The symptoms vary depending on the tumor's size and location. A lump or swelling might be noticeable, sometimes with pain, sometimes without.

- Key Characteristics:
- Malignant (cancerous) tumor
- Originates in muscle cells
- Most common soft tissue cancer in children and adolescents
- Symptoms vary based on tumor location and size
2. Relapsing Multiple Sclerosis (RMS): A Neurological Disease
Relapsing multiple sclerosis (RMS) is a form of multiple sclerosis (MS), a chronic and progressive disease damaging the central nervous system (CNS). In RMS, individuals experience distinct periods of relapse (flare-ups) and remission (recovery). [Source: PLEGRIDY, Johns Hopkins Medicine, National MS Society]
- Key Characteristics:
- Progressive neurological disease
- Characterized by relapses and remissions
- Damages the central nervous system
- Most common type of MS
Therefore, the meaning of "RMS" depends on the context. It's crucial to clarify which disease is being discussed to avoid confusion.
