Macrophages as a means of cancer treatment? ? does it actually work? has it been tested on people?

Cancer can be combated with reprogrammed macrophage cells.
Researchers have generated antibodies that reprogram a type of macrophage cell in the tumor, making the immune system better able to recognize and kill tumor cells. The study, say the scientists, could lead to a new therapy and provide a potentially important diagnostic tool for breast cancer and malignant melanoma.

Ibelieve the answer is relative humidity  because it makes more sense that way. solar flares usually occur in space it doesn't affect the earth, well it could but it wont make a significant damage.  latitude is land it doesnt do anything. prevailing winds, i dont know the correct meaning for this but i doubt that affects the land so it has to be relative humidity.
