Whether you can apply for subsistence allowance after getting cancer depends on the actual situation and needs to be reviewed. Article 66 of the Interim Measures for Social Assistance stipulates that families with family cars and large-scale agricultural machinery worth more than 50,000 yuan that can be used normally are excluded from giving, do not belong to poverty alleviation targets, and cannot enjoy subsistence allowances. Therefore, if you have cancer and have a loan car under your name, you can't do subsistence allowances.
