Doctorate at a University that we don't know, it was already at that time a character of relief, which held the position of doctor of the Royal House since at least three years before. During his stay in America, it was devoted to clinical practice, and won praise from Christopher Columbushimself as a physician. On the other hand, he/she demonstrated his talent for scientific observation in a letter addressed to the Seville Town Hall, which was one of the first reports about the nature of the new world and the customs of its inhabitants. It includes an excellent overview of the Antillean rodent called "Guinea pig" and other animal species, but especially noted for its botanical contents.

At the end of the text, it offers a more detailed botanical catalogue, which was incomplete. The letter was not printed in its time, but reached a remarkable diffusion through handwritten copies.
On his return to the peninsula in 1495 or 1496, Álvarez Chanca settled in Seville, where he/she arrived to enjoy a good economic position thanks to the practice and some commercial activities related to America. During the two decades of life he/she had published three works: a study of fascination or an "evil eye" (1499), a treatise on "evil side" (1506), on the occasion of a pestilenciales fever suffered in the region of Seville, and a comment to the Parabolae medicationis of Arnaldo de Vilanova (1514).
