What’s the difference between?
Tumour and cyst
A cyst is a bag filled with air, fluid or other material. A cyst can form in any part of the body, including bones, organs and soft tissue. Most cysts are non-cancerous (benign). Common examples of cysts include sebaceous cysts, small bumps that form just beneath the skin, and ovarian cysts. Nearly all cancers are capable of producing cysts.
A tumour is any abnormal mass of tissue and can form in any part of the body. A tumour can be benign or cancerous (malignant). To determine whether a cyst or tumour is benign or malignant, a sample is taken and studied.
