Difference Between '癌' and 'がん' in Japanese

While assisting individuals, I often encounter terms in brochures or online that spark my curiosity. In Chinese, terms like 'cancer' and 'tumor' are generally used broadly. Japanese also has similar general terms, but it's notable that both the kanji character '癌' and the hiragana 'がん' are frequently used. What exactly is the distinction between them?

Upon investigation, one perspective suggests that '癌' (kanji) specifically refers to malignant tumors originating in the respiratory or digestive tracts, such as lung cancer, stomach cancer, or breast cancer, which typically arise from epithelial cells. In contrast, 'がん' (hiragana) is a broader term encompassing all malignant tumors, including those of non-epithelial origin like sarcomas and leukemias. This information is provided for your reference to better understand Japanese medical terminology.
