• A. Blood
• B. Lymph
• C. Secondary growths of malignant tumour
• D. All of the above

Answer 1

The correct option is D All of the above

Cancerous cells spread to other parts of the body as it is able to break away from the original (primary) tumour and get into the bloodstream or lymph system, which can carry them to another part of the body. Cancerous cells also spread through metastasis. Metastasis is the development of secondary malignant growths at a distance from a primary site of cancer. When tumour cells metastasize, the new tumour is called a secondary or a metastatic tumour, and its cells are similar to those in the original or primary tumour.

So, the correct answer is 'All of the above'.
