What is the ruling of Islamic law regarding the work of an unmarried female doctor specializing in internal medicine, liver, and digestive system, which requires significant effort and time, and involves mixing with men? And must she give up her specialization for the sake of her future family life?

If a medical specialization will compel a woman to touch men, mix with them, and expose their private parts, then she must abandon it and seek another specialization that does not involve these prohibitions, such as gynecology and pediatrics. This is especially true if it conflicts with the woman fulfilling the rights of her husband and children.
