Question

Spread of cancerous cells to distant places is

• A. Malignancy
• B. Metastasis
• C. Mutations
• D. Benign tumour

Answer 1

The correct option is B Metastasis

Metastasis is a spread of cancerous cells from an initial or primary site to a different or secondary site within the host's body. When tumour cells metastasize, the new tumour is called as a secondary or a metastatic tumour and its cells are similar to those in an original or a primary tumour. Metastatic tumours are very common in the late stages of cancer. The spread of metastasis may occur via the blood or the lymphatics. The most common sites for the occurrence of metastasis are the lungs, liver, brain, and the bones.

So, the correct answer is 'Metastasis'.
