Chemotherapy and medications can cause:
- Metallic breath
- Strong body odor
- Changes in smell perception
This is due to treatment—not the cancer itself.
8. General “Unusual” Body Scent
Cancer cells release volatile organic compounds (VOCs)—tiny chemicals that can change body odor.
Scientists are even studying these smells for early detection, but:
- Humans usually can’t detect them
- Special tools or trained dogs are needed
The Truth You Should Know
- Most body odors are NOT cancer
- Common causes include:
- Hygiene
- Diet (garlic, onions)
- Hormones
- Stress
- Infections
Even when cancer causes odor, it’s usually:
- Rare
- Late-stage
- Linked to complications (infection, wounds)
