hi everyone. I don't know if this goes here or health questions. a question came into my head while reading about natural remedies. it said a particular plant had shown success in reducing tumors in lab rats. my question is, how would the scientists know the mice had tumors? might this mean they caused the tumors?

haha... ive never thought of this... i suppose they induced a tumor in some way of genetic engineering... they were able to grow a human ear on a mouse's back... a tumor shouldn't be too hard

Oohhhhhh. Rats! Well they get sick too you know. Rats get twomoors, we get three so I suppose that make things a little more difficult to create. All goes to improve the quality of our Jeans....they get less tear and last a little longer. Scientific enough?

Hahaha... funny and interesting question. I think the rats have human behavior most often and it is easy to learn them

Does the term "lab rats" not give it away? Of course those tumours were caused deliberately in the laboratory.

thank you to all for sharing your comments. I know some of my questions make me sound like a dummy, but I don't mind if it helps me understand. so I appreciate it.

I kind of think this, but then it leads to questioning the validity of the results that they present

Usually there are diagnostic markers elevated in blood sampling which can be indicative of tumours .. Or diagnostic radiology .. Can't imagine them doing the latter on a rat .. Laughing . Quite likely the tumours where created in the lab as is usually the way with laboratory animals .... Poor little sods :-( thank you for explaining this. the part about the diagnostic markers makes sense.

thank you Conrad for the simplicity of your answer and Metalwing, thank you for the visuals. . Pringle you made me laugh . Pansy and Catalia your comments were interesting too.

Yes, they give the entire set of rats cancer. Then they split the group in half. The control group gets no help. All rats eat the same food, drink the same water, have the same exposure to light, dark, comfort in the cage, fresh air, human contact, noises as the other group. The only difference is that the other group is given the medicine being tested. Both groups are tested weekly....even daily. Their data is checked over and over again. Then....they get another group....give them all cancer and do the whole spiel again and again to make sure the findings can be repeated. Is this humane? Not really. Are they abused otherwise? No. The thing is, we have to be sure that the medicines do not kill or cause other problems before testing can begin on humans. Keep in mind, humans sue....rats do not.

Which of the rats turn into politicians?

Most likely, the rats were injected with a particular tumors cells, so that they could determine if their new drug or method would work. It gives them a pretty good idea, but since the blood is different from rat to man, it is only a preliminary test. Until anything is actually tested on a human being, through a test group, nothing can be determined for sure but a test on another mammal, gives them a start.
