Why swelling in foot after chemotherapy treatment for lung cancer?

Swelling in the foot after chemotherapy treatment for lung cancer can occur due to several factors, including fluid retention, inflammation, or damage to blood vessels caused by the chemotherapy drugs. Additionally, chemotherapy may weaken the immune system, making the body more susceptible to infections that can also lead to swelling. It's essential for patients experiencing this symptom to consult their healthcare team, as it could also indicate other complications that need to be addressed.
