Cancer hates nicotine.
The article is about non smokers...
“Cancer hates nicotine”
Is that why some long term smokers who quit, suddenly develop cancer?
“Cancer hates nicotine.”
Not according to AI:
Nicotine is generally classified as a tumor promoter rather than a direct initiator of cancer, meaning it does not typically cause the initial DNA mutations that start cancer but significantly accelerates the growth, spread, and severity of existing tumors.
Research indicates that nicotine facilitates cancer progression through several mechanisms:
Cell Proliferation and Survival: It activates nicotinic acetylcholine receptors (nAChRs) and β-adrenergic receptors, triggering signaling pathways (such as PI3K/Akt and MAPK) that increase cell division and inhibit apoptosis (programmed cell death).
Metastasis and Invasion: Nicotine promotes epithelial-mesenchymal transition (EMT) and enhances cell motility, allowing cancer cells to invade surrounding tissues and spread to other organs like the lungs and brain.
Angiogenesis: It stimulates the formation of new blood vessels, which supply tumors with the oxygen and nutrients needed for rapid growth.
Treatment Resistance: Exposure to nicotine can reduce the effectiveness of chemotherapy and radiotherapy, leading to higher rates of tumor recurrence and decreased survival in cancer patients.
