In clinical observations, certain cancers exhibit a striking gender disparity—lung cancer rates in men surpass women by 60%, while liver malignancies affect males twice as frequently. From the perspective of Traditional Chinese Medicine (TCM), this phenomenon correlates with excessive "heart fire" and disrupted yin-yang equilibrium. Men often accumulate internal heat through prolonged stress, alcohol consumption, and irregular sleep patterns, manifesting as rapid pulse, night sweats, and irritability. Modern physiology reveals this translates to heightened sympathetic nervous system activity, causing oxidative stress that damages DNA in epithelial cells lining the lungs and liver. The autonomic imbalance disrupts circadian regulation of cortisol and melatonin, weakening immune surveillance against precancerous lesions.

TCM emphasizes "nourishing yin to subdue yang" through cooling herbs like chrysanthemum and rehmannia, paired with acupressure at Pericardium 6 (Neiguan) to soothe heart fire. Western medicine complements this with strategies targeting cardiovascular health: omega-3 supplementation reduces vascular inflammation linked to tumor angiogenesis, while melatonin rhythms normalization enhances DNA repair mechanisms. Practically, men should prioritize cooling foods such as cucumber and mint tea during summer months, avoiding spicy dishes that exacerbate internal heat. Regular tai chi practice synchronizes breath with movement, harmonizing sympathetic-parasympathetic balance more effectively than static stretching. For those with a history of smoking or hepatitis, combining TCM's "clearing lung heat" formula (containing Scutellaria baicalensis) with low-dose aspirin creates a synergistic anti-inflammatory shield against carcinogenesis.
