Researchers find two connective tissue cells to be linked to worse prognosis of breas
 

In certain forms of cancer, connective tissue forms around and within the tumor. One previously unproven theory is that there are several different types of connective tissue cells with different functions, which affect the development of the tumor in different ways.

They dont mention this specifically but on eof the main cancer growth metastasis etc stimulating chemicals is a Cytokine called Interleukin-6. This is what these fibroblasts in the tumor environment secrete. In fact, the cancer cells can secrete chemicals to attract these Interleukin-6 secreting fibroblasts.

The bone matrix is chock full of Interleukin-6 secreting cells. This is believed to be the basic reason so many cancers metastasize to the bones. They go where the Interleukin-6 is.

There is an anti-Interleukin-6 drug called Siltuximab, brand name Sylvant. I thing the dose is 11mg/KG every three weeks, maybe every month. Perhaps this drug might be useful in treating cancers of various types.
