15 Common Warning Signs of Cancer

Have you ever:

• Noticed your shoes feel tighter than usual?

• Seen one foot or ankle puffier than the other?

• Pressed your skin and left a dent that lingers?

You’re not imagining it.

Swollen feet or ankles — medically known as edema — are more than just a sign of a long day on your feet. While they’re often harmless, sudden or persistent swelling can be a silent signal from your heart, kidneys, veins, or lymphatic system.

Ignoring it could mean missing an early warning sign of a serious condition.

Let’s explore the common causes of foot swelling, when it’s normal, and when to see a doctor — so you can respond with awareness, not fear.

🧠 What Is Edema?

Edema is the buildup of fluid in the tissues — most commonly in the feet, ankles, and legs.

It can be:

• Mild and temporary — after standing too long or during hot weather

• Chronic or sudden — a clue that your body needs attention

🔍 Simple test: Press your finger into the swollen area. If it leaves a dent (called pitting edema), it’s likely fluid retention.

✅ Common & Harmless Causes

In many cases, swollen feet are nothing to worry about — especially if they go away with rest.

• Prolonged standing or sitting

• Heat or humidity

• Salt-heavy meals

• Hormonal changes (PMS, pregnancy, menopause)

• Minor injury (sprained ankle, foot strain)

These usually improve with:

• Elevating your legs

• Moving around

• Reducing salt intake
