Why Are There Weeks Between The Big Chemotherapy Sessions?

Why are there weeks between each big Chemotherapy Sessions? The reason for this is because it takes you nearly 3 weeks to recover from all the Chemotherapy and it's side effects. For me once the steroids wear off on the Friday after the Chemo I do be pretty ill for a straight 8 days after. Not everyone is the same and some people take longer or quicker then others to recover each person is different and recovers in their own time. So many side effects go on at the same time for me things like dry mouth, tiredness, weakness, stomach cramps, feeling sick, broken sleep, sore bones from the Neulasta. After the 8 days I start to feel a bit better except for the tiredness that seems to stay with me. The second week after Chemo is when your immune system goes down and you have to be very careful around people that are sick with colds and other illnesses. The third week after Chemo you start to feel a lot better then it's time to have some more Chemotherapy so your body really does need time to recover before it has to be able to take the next dose of Chemotherapy.
