Red spots, bumps, or patches can appear for many reasons. Some are common and harmless, like:

• Acne are red or swollen bumps
• Eczema is itchy, red, dry patches that may crust
• Hives is sudden red bumps from allergies
• Rosacea is small red pimples, usually on the face
• Heat rash is itchy red bumps from sweat
• Bug bites is small, itchy, swollen spots
• Keratosis pilaris is tiny hard bumps around hair follicles
  

Other causes can include boils, cold sores, sun allergies, or skin growths like angiomas. Chronic conditions like psoriasis may also appear as red, scaly patches. 

Rarely, red spots can signal serious conditions such as infections, autoimmune disorders, or skin cancer.

Red spots may need medical attention if you notice:

• A bump or spot that doesn't go away
• A spot that changes in colour, size or shape
• Spots that appear suddenly without reason
• Any spot that looks suspicious or causes concern
  

Skin cancer, from melanoma to basal cell carcinoma, can sometimes appear as red spots, scaly plaques, or unusual moles. Early detection is key to effective treatment.
