Why is the Survival Rate of Cancer Patients in Japan Increasing?

A research team from Kyoto Prefectural University of Medicine recently published a paper stating that the risk of developing breast cancer increases by 36% for women who sit for more than 7 hours a day.

Led by researcher Hitomi Tomita, the team collected data from over 36,000 cancer patients from university-affiliated hospitals and the National Cancer Center, among other medical institutions nationwide. Their report reveals that, among 554 female breast cancer patients studied, those who sat for more than 7 hours a day had a one-third higher incidence of breast cancer compared to those who sat for less than 7 hours. Tomita explained that prolonged sitting leads to inactive muscles, causing hormonal imbalances and consequently raising the risk of breast cancer.

The research team suggests that the best prevention for breast cancer is walking for at least one hour a day and engaging in physical activity three times a week. Particularly for women working in offices, it’s recommended to stand up and move around after sitting for a prolonged period.

While the incidence of breast cancer among Japanese women is relatively high, with one in nine women developing breast cancer, recent years have seen a significant improvement in the survival rates of cancer patients in Japan.

According to the latest statistical report from the National Cancer Center published on January 25, the ten-year average survival rate for 360,000 patients diagnosed with cancer in 2011 has reached 53.5%, a 0.2 percentage point increase from the 2022 data.

The ten-year survival rates for specific cancers are as follows: prostate cancer at 85.4%, breast cancer at 82.9%, colorectal cancer at 57.9%, and stomach cancer at 56.8%.

For the first time, the National Cancer Center has also disclosed the ten-year survival rates for the AYA generation (15-39 years old):

  • Leukemia: 70.6%
  • Lung cancer: 39.1%
  • Breast cancer: 84.0%
  • Bladder cancer: 72.0%
  • Uterine and cervical cancer: 87.7%
  • Stomach cancer: 59.7%
  • Liver cancer: 36.4%
  • Colorectal cancer: 70.5%
  • Brain tumor: 78.2%
  • Lymphoma: 86.6%
  • Thyroid cancer: 99.4%
  • Kidney cancer: 72.0%

Researchers at the National Cancer Center attribute the continuous improvement in the ten-year survival rate of cancer patients in Japan to the development of targeted drugs based on immune cells, led by Professor Honjo Yoshio of Kyoto University. With the accelerated development of new drugs, the survival rate of cancer patients is expected to further increase.
