Th1/Th2 balance: the hypothesis, its limitations, and implications for health and disease. Kidd P. Altern Med Rev. 2003 Aug;8(3):223-46. Review. PMID: 12946237 Th1 pathways typically produce activation of cytotoxic T lymphocytes (Tc), NK cells, macrophages, and monocytes, all of which can attack cancer cells and generally defend against tumors. 55 IFN-gamma and other Th1 cytokines are typically lower in advanced cancer patients, while the Th2 marker IL-4 can be higher or unchanged.56 Nodules of non-small cell lung cancer freshly removed from patients expressed a marked imbalance toward Th2, as did biopsy samples from basal cell carcinoma.57 In prostate cancer patients IL-2 was low (Th1) and IL-10 high.58 IL-10 is a confirmed Th1-suppressive cytokine, and heightened IL-10 is a common factor in cancer.55 IL-10 has a variety of suppressive effects that include inhibiting Th1 cytokine production, down-regulating APC and NK cell function, and lowering overall T-cell proliferation.57 Especially under the influence of IL-4 (Th2), tumor cells apparently up-regulate IL-10 that suppresses nearby killer cells. Tumor-derived IL-10 has been documented in lymphoma, ovarian carcinoma, melanoma, neuroblastoma, and renal cell and colon carcinoma.57 IL-12 is another cytokine that can be up-regulated by Th1 activity and inhibited by Th2.59 A low IL-12/IL-10 ratio was found in cervical cancer patients.55 Recent clinical studies suggest elevated IL-10 is predictive of a poor prognosis. 57 With both IL-4 and IL-10 being proven inhibitors of Th1 and promoters of Th2 activity, the recognized capability of cancerous tissue to suppress immunity is readily rationalized.

Fish, vitamin D, and flavonoids in relation to renal cell cancer among smokers. Wilson RT, Wang J, Chinchilli V, Richie JP, Virtamo J, Moore LE, Albanes D. Am J Epidemiol. 2009 Sep 15;170(6):717-29. Epub 2009 Aug 3. PMID: 19651663 doi:10.1093/aje/kwp178 These results suggest that the flavonoid quercetin may prevent renal cell cancer among male smokers. The possible risk associated with fish intake warrants further investigation before conclusions may be drawn.
