Why it matters:
Leukemia or lymphoma can crowd out healthy blood cells, causing anemia
Colon or stomach cancers may cause slow internal bleeding → anemia → fatigue
Liver cancer impairs toxin processing, leading to systemic strain
📌 When to act: If fatigue lasts >2 weeks and isn’t tied to stress or poor sleep, get checked.
⚠️ 3. Unusual Skin Changes
Your skin can reflect internal health. Watch for:
Moles that change size, color, or shape—or have irregular borders (melanoma)
Sores that don’t heal after 4+ weeks (possible squamous or basal cell carcinoma)
Yellowing of skin/eyes (jaundice)—linked to liver or pancreatic cancer
Dark patches, redness, or intense itching without rash (may signal lymphoma or internal cancers)
📌 When to act: Any new, changing, or non-healing skin lesion needs evaluation by a dermatologist.
⚠️ 4. Chronic Pain That Won’t Go Away
Pain that persists for weeks despite rest, hydration, or OTC meds should never be ignored.
Possible causes:
Bone pain → bone cancer or metastasis
Headaches + nausea/vision changes → brain tumor
Pelvic/abdominal pain → ovarian, uterine, or colorectal cancer
Chest pain → lung cancer or mesothelioma
