It also could be her significant other searching about funeral costs and arrangements. I highly doubt it was chemotherapy because the ROAS would be insanely small especially for mail based marketing($0.50 per touch at least). Person isn't dead and could recover. If the cancer is terminal it still could take years. Sometimes its better not knowing why you received that type of marketing.
