It does sound as though your mom's doctor isn't taking an aggressive approach to an aggressive disease. I didn't think my dad's oncologist was either. But in comparison, he's very aggressive. My dad currently has a team of doctors, whom which monitors him closely. He's had multiple MRIs and Ct scans since his diagnosis. He just went in on Sunday for an MRI and did another on Wednesday (first non ink and the second with ink). He has an appointment this upcoming Wednesday to have his blood work done to see if it has metatasized into the bones and/or glands.
My dad completed his radiation with little side effects (so we think). He had 20 treatments total. However, his has spread to his brain, so they only did radiation therapy to his brain. Shortly after radiation, his hair began to shed tremendously. So we've shaved it off completely. But it has started to grow back fairly fast. He also had an episode where he appeared to be a bit delusional, with violent outburst. He was admitted into ICU for two weeks. During this time; he was unable to speak, walk, or anything. The hospital staff had the family speak to a social worker and recommended hospice. They also wanted us to give them the consent to put a breathing tube in. We didn't allow them to do this because they informed us that if there did put the tube in, it would be permanent as his lungs were too weak to remove the tube. Which means, he would've had to stay in the hospital indefinitely. During this time, we were devastated as it appeared as though we were going to lose him. With lots of prayer and faith, my dad pulled through. He was released from the hospital with a hospital bed, wheelchair, and portable 3 in 1 pottychair. They attempted to tell us that they were requiring him to be placed in a skilled nursing facility. We strongly opposed. He is now able to walk, speak and eat on his own. It was a challenge because we had to teach him everything all over again. This all happened less than a month of his diagnosis. All this being said because the doctors didn't know if it was a negative side effect from the radiation or not. They recommended he not receive anymore radiation.
I find it strange they scheduled your mom's chemo so far apart. Everyone I know who has had to complete chemo, had to complete them consecutively for a while. Did your mom experience nausea, loss of appetite, or weak?
