Hi Hannah
I personally wouldnt delay any type of cancer treatment, you have young children, i also live on a farm and have young kids, they were alot younger when i had cancer treatment, i too am 3 and a half hours away from the city but we just had to make it work, it meant my husband couldnt be with me but other family members rallied around to help, you need to have the treatment and timing can be crucial, put yourself first just this once and get yourself better for your husband and kids, best of luck xx
