Question

In metastatic cancer:

	1.	The metastasis is easy to detect
	2.	Standard of care is an effective treatment
	3.	is a rare type of cancer
	4.	is due to defect in the production of antibodies
	5.	none of the above

Answer 1

none of the above.

metastasis is the movement of cancerous agents to a new site in the body. For example, assume lung cancer in its benign state confined to lungs but when a benign state undergoes epithelial to mesenchymal transition, the cancerous cells are now able to move to a new location in the body through the blood this state is known to be metastatic.

1. these are not easy to detect, this is ongoing field research where people are trying to detect circulating tumor cells. Researchers are now successful in detecting metastatic cancers with the advent of technology. but it is not easy to detect compared to benign lumps.

2. metastatic are more dangerous to a patient than benign. hence would require a lot of work to cure.

3. It's not a type of cancer, rather a stage of cancer. lung cancer can have benign and metastatic state, breast cancer can have a benign and metastatic state. latter being more critical state

4.antibodies have not much to do with metastasis. the fact the antibodies could be used to inhibit proteins that play a role in metastasis is a whole diffrent field of cancer research.
