Tomizo Yoshida (吉田 富三 Yoshida Tomizō, 1903–1973) was a prominent Japanese pathologist, famous for discovering the Yoshida Sarcoma. In addition, he is known for demonstrating the chemical-induced hepatocarcinogenesis in rats with his mentor Takaoki Sasaki.
Yoshida received the Imperial Prize of the Japan Academy twice (1936 and 1953) as well as the Robert Koch Gold Medal (1963).
Contribution
In the 1930s Tomizo Yoshida and Takaoki Sasaki showed the induction of liver cancer in rats by Ortho-Aminoazotoluene.[1] Since that time, a large amount of data has confirmed the carcinogenic activity of Azo dyes.[2]
In 1943, Yoshida found a cancer cell line, so-called Yoshida Sarcoma,[3] and experimentally proved that cancer is generated from cancer cells. His findings opened the way of cancer research in terms of cells, and developed biomedical research on chemotherapy.[4]
Biography
Yoshida was born in Asakawa, Fukushima and graduated from the Medical School, Imperial University of Tokyo in 1927.[5] He was an assistant professor of pathology at the same institution from 1927 to 1929.[5] In 1929 he moved to the Sasaki Institute to work on chemical-induced carcinogenesis with Takaoki Sasaki, before he went to Germany to study pathology in 1935.[5] After returning to his homeland, he served as a professor of pathology at Nagasaki University from 1938 to 1944, Tohoku University from 1944 to 1952, before being appointed as a professor of pathology at the Faculty of Medicine, University of Tokyo in 1952, where he became a dean in 1958.[5] In addition, he became a director at the Sasaki Institute in 1953 and at the Cancer Institute, Japanese Foundation for Cancer Research in 1963.[5] He died in 1973 at the age of 70.

Yamagiwa-Yoshida Memorial international study grants
After his death, Japanese cancer researchers established the Yamagiwa-Yoshida Memorial international study grants in honor of Katsusaburō Yamagiwa and Tomizo Yoshida.[8] Since its inception in 1975, the grants supported by UICC Japan National Committee have contributed to the development of the professional capacity of over 330 Fellows from over 40 countries.[9]
