What is the difference between swelling and lump?

Swelling refers to an abnormal enlargement in the size of a body part or tissue due to an increase in fluid, blood, or gas. It appears as puffiness, distension, or bulging of the affected area. Causes of swelling can vary, such as inflammation, fluid retention, infection, injury, allergies, or underlying medical conditions.

On the other hand, a lump is a noticeable, localized bump, mass, or growth on the body that feels solid or semi-solid and is distinct from the surrounding tissue. Lumps can occur anywhere on the body and vary in size, shape, and consistency. Unlike swelling, which may resolve or fluctuate, lumps generally persist or even grow over time. They can develop due to several causes, including abnormal cell growth, infections, cysts, tumors (benign or malignant), enlarged lymph nodes, or tissue changes.

Symptoms associated with swelling or lumps depend on the underlying cause. Swelling may be accompanied by pain, tenderness, warmth, redness, or restricted movement if it's caused by inflammation or injury. Lumps may cause discomfort, pain, skin changes, or interfere with bodily functions depending on their nature and location.

If you notice unusual swelling or a lump on your body, it's important to see a healthcare professional promptly for proper evaluation. They can conduct examinations, imaging tests, or biopsies to determine the cause and recommend appropriate treatment or management.
