How long does a cancer patient have to live when the cancer has spread to the lymph nodes?

I'm sorry about your dad. Each person is different. Your father's doctor will have to answer these questions, though even medical people are often hesitate to put a timeline on someone's life. However, you may want to talk to the doctor to see if hospice care is something to consider in the near future. The can help keep him comfortable. People qualify for hospice care who have been diagnosed as having six months or less to live. Hospice personnel are generally very good about answering questions about the patient's health.
Take care of yourself, too.

my 98 yr old mom has metastic breast cancer that has spread to her chest wall, ribs and lymph nodes along with many tumors in her breast. This is her second bout with breast cancer. First time was 34 yrs ago. This time it started 11 yrs ago. PET scan does not show any tumors in her brain but she has been complaining of head pain for last 2 mos. She has become very agitated lately and her skin is very itichy. The doctor has said she has 6-12 mos but that is if the cancer continues slowly if not it will be less. Does all of these latest developments mean anyhting and does anyone know of any solutions for the itching??? I hate to call the doctor every week with all of these questions. Any suggestions??

I have stage 4breast cancer and cancer has spread it is now active in the jugular and lymph nodes in the neck, and now my arm is swollen. I had this round with breast stage for 7 years. How long do I have

If your arm has suddenly swollen up, get to the ER, don't just assume this is part of the cancer. Get a proper diagnosis.

Given that it's metastasized to your lymph nodes, it could be lymphedema, which causes extensive swelling when the body (and lymph system) is not able to move fluid out for excretion.
