Lung cancer begins in the lungs and may spread to lymph nodes or other organs in the body, such as the brain. In fact, symptoms may not show until the cancer has spread to other regions. One telltale sign the cancer is having knock-on effects is pins and needles in your toes or fingers.
According to Macmillan Cancer Support, pins and needles in affected areas can be a sign of peripheral neuropathy (also called neuropathy).
Peripheral neuropathy is a term used to describe damage to the nerves that carry messages between the brain, the spinal cord and the rest of the body.
Although the damage is usually attributed to cancer drugs, it can be the result of “paraneoplastic syndrome”, explains Macmillan.
Paraneoplastic syndrome is where the body makes substances that damage peripheral nerves.

This can happen with types of cancer such as lung cancer, myeloma or lymphoma.
Other telltale signs of peripheral neuropathy include:
- Muscle weakness
- Constipation and feeling bloated
- Feeling light-headed or dizzy when you sit up or stand up
- Difficulty buttoning clothes or picking up small objects
- Difficulty with balance, walking and coordination.

“The GP will ask about your general health and your symptoms,” explains the NHS.
According to the health body, they may examine you and ask you to breathe into a device called a spirometer, which measures how much air you breathe in and out.
It adds: “You may be asked to have a blood test to rule out some of the possible causes of your symptoms, such as a chest infection.”
Am I at risk?
There are some factors that can increase your risk of developing lung cancer.
Some chemicals and substances increase the risk of lung cancer.
Research suggests that being exposed to diesel fumes over many years increases your risk of developing lung cancer.
One study has shown your risk of developing lung cancer increases by around 33 percent if you live in an area with high levels of nitrogen oxide gases (mostly produced by cars and other vehicles).
Other chemicals and substances include:
- Coal and coke fumes
