Mostly depends on tumor type.
Breast tumors, when they carry the estrogen receptor (ER), are stimulated by estrogens and slowed with antiestrogen. Same goes for endometrial or ovarian tumors.
Prostate or testicular tumors will likewise be stimulated by androgens and slowed with antiandrogens if they carry the androgen receptor (AR).
In leukemia, if the cells carry the glucocorticoid receptor (GC), they will be slowed by cortisone (this is why kids with leukemia are given high doses of cortisone which causes swelling in the face).
Also, there are now, in final clinical testing stages, new medication which will slow the growth of most solid tumors by keeping them from creating their own blood vessels. This new class of medication is called anti-angiogenics.
And the most recent strategies that are being developped now involve blocking the free moving cell's adhesion to organs, and in that way keeping a tumor form metastasing.

If it was known, we would have a cure to stop it.
There are some reasons which are known. For example, something is telling the cells to divide although the body doesn't need them to divide. At the same time something blocks the apoptosis mechanism of the cells (apoptosis is programmed cell death and is essential for all living organisms) so they don't die after they have divided too often. For an agent to achieve this, it has to alter the DNA of the cells. Some known agents are radiation, some viruses (yes, cervical cancer is caused by a virus and is therefore contagious), and the above mentioned free radicals. But it is possible for a tumor to grow because of other reasons, which are still not known to today's scientists.

Do a websearch on Essiac Tea. I am hearing a lot about this in regards to slowing and reducing tumor growth.

Depends on the type of tumor you are talking about.
Radiation therapy is often used to stop and reduce the proliferation of cancer cells.
Chemo therapy treatments with things like Cisplatin help the effectiveness of the radiation

Tumor growth is caused by the abnormal proliferation of cells. Free radicals floating around in the blood stream are thought to contribute to cancer. Food high in anti-oxidants are thought to fight these free radicals.

it has been proved that the chinese have alot less cancer tumors than the rest of the world - so if you stick to a non diary, non red meat, no sugar diet, it helps!!
the statics were something really strange like in china 1 in 10000 get breast cancer yet here in the uk its like 1 in 10!!!
try reading the books by jane plant

That question is too vague unless you can identify the type of tumor.
Do that and then google the specific name and search.
