You can apply for the CUME benefit from the National Social Security Institute (INSS), a subsidy that compensates for the loss of income suffered by working parents, adoptive parents, or foster parents who reduce their working hours (by at least 50%) and their salary to provide direct, continuous, and permanent care for a dependent child affected by cancer or another legally defined serious illness. You can find information about the requirements and application process for this benefit on the website of the Ministry of Inclusion, Social Security, and Migration.
