IPA: /nɒnˈkænsərəs/
KK: /nɑnˈkænsərəs/
Referring to a condition or growth that is not cancerous and does not pose a threat to health.
The doctor assured me that the tumor was noncancerous and not a cause for concern.
Noncancerous → It is formed from "non-" (meaning not) and "cancerous" (from Latin "cancer" meaning crab, used in a medical context to refer to cancer). The word "noncancerous" means not having cancer or not related to cancer.
Think of 'non-' meaning 'not' and 'cancerous' referring to cancer — so noncancerous means not related to cancer.
