In 2023, the mortality rate for trachea, bronchus, or lung malignant neoplasms in Japan stood at 88.0 male deaths per hundred thousand men. Forecasts predict a gradual increase from this baseline, reaching 88.3 in 2024 and rising incrementally each subsequent year to 89.8 by 2028. This reflects an annual growth trend of approximately 0.4%, culminating in a compound annual growth rate (CAGR) of about 0.4% over the five years from 2023 to 2028.

Future trends to watch include:

Impact of healthcare innovations on early diagnosis and treatment efficacy.
Population demographics, particularly aging trends which could affect cancer prevalence.
Policies aimed at reducing smoking rates and exposure to pollutants, key risk factors for these cancers.
