natural remedies for shrinking/getting rid of tumors?

my mom just came to me and told me she had a tumor that started growing on her ankle in 2009, and has since wrapped around the bottom of her foot, and it’s been causing her pain to walk lately. She’s had a benign tumor on her arm before, and was able to have it removed. Her chances for getting cancer are huge. She has a lot of sun damage on her skin and has also been smoking for more than 20 years. Since a messy custody battle with my ex-stepfather, she has had her insurance taken from her and is really on the edge with money. (as in only receiving 0 a month.) I just want to have her try an at-home remedy that will make me feel safer about her health until she gets another job.
