When cancer cells enter the lymph or blood system,

Question

Quizplus · Accepted Answer

When cancer cells enter the lymph or blood system, they can travel to other parts of the body and form secondary tumours, a process called metastasis. This can make the cancer more difficult to treat and lower the probability of cure. Thus, option D is the correct answer. Options A and B are incorrect because entering the lymph or blood system does not increase the probability of cure or make the cells benign. Option C is also incorrect because it is not easy to stop the spread of cancer cells once they have entered the lymph or blood system.
