Good morning, @pike70 Chronic Lymphocytic Leukemia (CLL) is a cancer of the blood in a group of white blood cells called lymphocytes, which help your body fight infection. CLL most commonly affects older adults and it’s often found incidentally with a routine blood test. Because it is very slow to progress, it’s called chronic instead of acute and doesn’t require any treatment until the disease starts to show signs of proliferation.

Most patients with CLL are asymptomatic at the time of diagnosis. As the disease progresses, some of the more noticeable symptoms are:
Chills
Swollen lymph nodes
Fevers
Night sweats
Shortness of breath
Frequent illnesses
Enlarged spleen causing abdominal pain or fullness
Tiredness
Unexpected weight loss
Enlarged liver

How you feel matters. So it’s important to contact your doctor if you experience chills, fever, or unexpected weight loss.
Only you know how you are feeling. If you’re feeling mentally or physically tired, or experience any of the symptoms mentioned, it’s important to speak up and tell your doctor.

I found a couple of links on our Mayo Clinic website that you might find helpful. They explain the disease, the progression and the possible treatments.

It sounds like you have a great family doctor to have caught your blood results, noting the changes and referring you to an oncologist/hematologist. This blood cancer doctor will be keeping an eye on your disease and making sure you stay healthy.
How often do you see your oncologist for follow up blood tests?
