Avaliação da superexpressão da proteína p53 e das mutações no éxon 8 do gene TP53 em carcinomas mamários caninos e glândulas normais Evaluation of immunohistochemical over expression of p53 protein and of mutations in exon 8 of Tp53
Some men and people assigned male at birth develop a condition called gynecomastia. This can cause breasts to be tender and may lead to a rubbery lump below the nipple. Sometimes this is in one breast, but it often happens in both. This lump isn’t cancerous. Gynecomastia can sometimes be...
