Cancer: Role of TCM in Treatment and Prevention

01 · Biology

From hallmarks to host. Why single-pathway wins rarely last

In 2000, Hanahan and Weinberg published “The Hallmarks of Cancer,” naming six acquired capabilities of cells progressing toward malignancy: sustaining proliferative signalling, evading growth suppressors, resisting apoptosis, enabling replicative immortality, inducing angiogenesis, and activating invasion and metastasis. Those traits have guided much of modern oncology since.

Updates in 2011 and 2022 expanded the map further, adding traits such as reprogrammed metabolism, immune evasion, phenotypic plasticity, senescent cells, and enabling factors including genome instability, tumour-promoting inflammation, non-mutational epigenetic reprogramming, and polymorphic microbiomes. From six hallmarks to a denser set of key traits, the picture of how cancer cells keep a growth advantage has grown more detailed, and more incomplete.

Intensive discovery will continue. Cancer cells already use multiple-pathway and pathway-switching strategies to slip past the barriers we put in place. Even when growth is slowed, the pause can be temporary. Tumour heterogeneity, from divergent evolution within a neoplasm, fosters genomic instability and clonal diversity. That diversity sits behind much of drug resistance and relapse, and is why many interventions remain palliative rather than curative.

Heterogeneity also complicates detection. A biopsy, the basis for many treatment choices, may sample only a fraction of cells that do not represent the whole tumour. Living solutions that revive host immune capacity, as in CAR-T approaches, aim further ahead. The durable answer keeps circling back to a resilient host. That is also where TCM oncology can meaningfully complement contemporary medicine.

02 · East meets West

Complementary strengths, not competing ones

Stable alliances share goals and beliefs, and bring complementary, non-competing skills. Contemporary medicine has an expanding arsenal for a capricious disease landscape. Those tools can stop cancer growth in its tracks, yet may lose efficacy over time, and they work best when the patient’s general health remains intact enough to tolerate them.

Some patients, because of deteriorating condition or harsh adverse effects, must defer treatment. Those gaps are costly when cancer cells remain active. Orthodox options often elicit a rapid response and may also take a toll on general health, sometimes leaving the patient more vulnerable to other pathogens even after the disease is brought under control.

An NHK documentary once featured a Japanese university surgeon who referred a post-surgical gastric cancer patient who was anorexic, emaciated, and non-ambulatory to a Kampo practitioner. After a course of herbal treatment, the patient could eat his favourite udon and literally walk in the park. The prescription was Six Gentlemen Decoction (六君子汤), a TCM formula from the Han era.

TCM’s lack of disease-level specificity can look like a shortcoming. In that gap sits a strength. Effort is directed at the patient rather than only the disorder, so care is moderated and whole-person rather than fixed narrowly on the lesion. Uplifting well-being is prioritised over a binary win-lose against the disease. As a last resort, that may mean peaceful coexistence with cancer (与癌共存).

Debilitation recovery (补虚) is a distinctive forte across TCM modalities. Debilitation is read as imbalance among interrelated organ systems under the Five Elements concept, which guides diagnosis and shifting treatment permutations as the patient’s condition changes. When orthodox cancer treatment’s constructive destruction is paired with TCM’s work on recovery, clinicians and patients sometimes see outcomes that neither approach produces alone.

04 · Stages

Four places TCM may sit beside modern care

These are practical staging aims when TCM is deployed with specialist oncology. Plans always depend on the patient’s reports, tolerance, and the oncology team’s advice.

05 · Choosing

How to choose a TCM counterpart for integrative care

On paper, an East-meets-West alliance looks ideal. In clinic, the two sides rarely confer on the same patient. The person with the most vested interest often becomes the matchmaker. Cancer is usually diagnosed in acute centres, so a specialist team is assigned from medical findings. The patient’s task is to find a TCM clinician who can hold a meaningful conversation with that team, with working knowledge of modern medicine, especially immunology and cancer biology.

Without watching that interaction, bring pathology reports, radiology, laboratory results, and discharge summaries to the first TCM consult. If the clinician treats those reports as irrelevant, integrative cancer care is unlikely. If commentary is missing or inconsistent with the wider picture, seek a second opinion before major herbal or treatment recommendations.

06 · Prevention

Prevention as maintenance, not magic

Cancer’s legacy stretches far beyond human history. Longer human lifespans have made its footprint more visible. Modern science has made real advances by rejuvenating immune capacity. The durable metaphor is still refurbishing the machine, not only chasing each new pathway.

Why wait for failure before acting? Two low-drama habits may help defer risk for some people: keeping a positive outlook, and supporting longevity practices that TCM has long treated as preventive maintenance. Murine models have linked higher happiness-related signalling, including dopamine, with better cancer outcomes in those settings. For “turning back the biological clock,” TCM’s longevity tradition is one place patients look. Neither path replaces screening, vaccination where indicated, or specialist advice.
