Question

During metastasis, where do cancer cells travel to form secondary tumours?

पर्याय

• Back to the primary site to reinforce the original tumour

• To new sites in the body via the bloodstream or lymphatic system

• Exclusively to the lymph nodes and nowhere else

• Only to adjacent normal tissues surrounding the primary tumour

Answer 1

During metastasis, cancer cells disseminate through the bloodstream or lymphatic system to reach distant organs and tissues throughout the body. These cancer cells establish themselves at new sites and form secondary tumours, which is why metastasis represents the most feared property of malignant tumours.
