4 Leg Symptoms That Could Signal a Deadly Cancer

4 Leg symptoms could signal a deadly cancer

Leg symptoms are often overlooked, but they can sometimes signal serious underlying health issues, including cancer. Persistent swelling, pain, numbness, or unusual skin changes may include warning signs that should not be ignored. Trying to pay close attention to these changes can help to detect problems early and improve the treatment outcomes. 

Here are some of the four leg symptoms that deserve medical attention, along with a clear explanation of why they matter.

Persistent swelling in one leg

Leg swelling is common and often feels harmless, especially in the beginning, but it persists after long periods of standing, sitting, or traveling. But suddenly, if you are experiencing sudden, unexplained, or one-sided swelling in your legs, it can be a warning sign of cancer.

Why this can be serious:

In some cancers, including lung, pancreatic, ovarian, stomach, and certain types of blood cancers, these can make the blood more likely to clot. These issues can lead to deep vein thrombosis (DVT), which is a medical condition where a blood clot starts to develop in a deep vein, usually in the legs.

Constant or Deep pain in one leg

If you are getting muscle strains, joint problems, and overuse injuries are common reasons for leg pain. However, an on-going pain that doesn’t improve or worsen overtime, without an obvious injury deserves a careful medical evaluation.

How cancer might cause leg pain, including:

• Bone cancer originating in the leg
• Cancer that has spread to the bones, such as breast, prostate, lung, or kidney cancer
• Tumors pressing on nerves or blood vessels
• Bone weakening that increases the fracture risk

Here are some of the reg flags to watch for:

• Pain that felts so deep, dull, or aching
• Pain that becomes worse at night 
• Pain that doesn’t improve with rest and medication
• Pain associated with swelling, weakness, or reduced mobility. 

Many experts suggest that cancer-related bone pain often progresses slowly and steadily, unlike typical injuries that improve with time.

Weakness, numbness or tingling in the legs

Temporary numbness from sitting awkwardly is usually harmless. But persistent, spreading, or worsening weakness or numbness in the legs can signal a serious underlying condition.

Here are some of possible cancer-related causes:

• Tumors pressing on the spinal cord
• Cancer spread to the spine
• Nerve damage caused by the cancer or immune reactions
• Certain blood cancers affecting nerve function

Cancers most commonly linked to these symptoms include lung cancer, lymphoma, multiple myeloma, and cancers that spread to the spine.

Seek an immediate medical evaluation, if you start to notice:

• Difficulty walking or standing
• Loss of balance or coordination
• One leg feeling significantly weaker than the other
• Sudden changes in bladder or bowel control

These symptoms may indicate spinal cord compression, which is a medical emergency. Getting an early cancer treatment can prevent nerve damage.

Unusual skin changes, lumps and non-healing sores on the leg

The skin of our body tends to generally reflect internal health issues, including cancer. While people with persistent skin changes or lumps on the legs should never be dismissed.

Here are some of the concerning signs, including:

• Experiencing firm or painless lumps beneath the skin
• Lumps that continue to grow
• Sore or ulcers that do not heal
• Darkening, thickening, or redness of the skin
• Painful nodules or unexplained rashes

Possible - cancer related causes

Here are some of the possible cancer related causes, which should not be ignored. These may include:

• Soft tissue sarcomas
• Skin cancers such as melanoma
• cancers that trigger paraneoplastic syndromes (immune-related skin changes)
• Cancers starts to spread to the skin from another organ

Key Note: If you are experiencing any lump that is hard, painless, larger than a few centimeters, or increasing in size, it should be examined by a healthcare professional.

When should you consult a doctor

You should seek an immediate medical evaluation, if you experience any of the leg symptoms, including:

• Persistent and progressive leg worsening 
• Unexplained injury or changes
• Affecting one leg more than the other
• Accompanied by fatigue
• Sudden weight loss
• Fever 
• Night sweats

Even if you haven’t experienced all of these symptoms or few, getting checked won’t mean you have cancer. It means that ruling out any suspicious and serious causes while treatment options are most effective.
