What is Leukemia?
The word Leukemia is derived from the Greek words leukos (white) and aima (blood). In simple terms, it is a cancer of the blood or bone marrow. It affects the forming of blood cells, one of the most important cells groups of the human body.
An abnormal production and accumulation of white blood cells characterizes this disease. This form of cancer starts to grow from the stem cells present in the bone marrow. Bone marrow is where blood cells are made.
The presence of abnormal cells called as leukemia cells?, also called as damaged leukocytes confirms the disease. Abnormal cells often over crowd with the other cells and end up with damaged DNA. The entire process makes it difficult for the other cells to do their functions smoothly.
In a healthy human, the W.B.C will die after a certain period resulting in the growth of fresh. In this case, they do not die easily and take-up space and continue to add-up. This crowding of bad cells, almost like a fission reaction in an uncontrolled manner, does not allow the normal functioning of the good cells and this result in sickness.
To better understand this disease, it is important that we know the related biological terms:
Bone Marrow:
The inner part of the bone is the bone marrow and this is where R.B.C, platelets and W.B.C are created
White blood cells (W.B.C):
They are also called leukocytes, and they primarily help fight infections. They are of three types:
Lymphocytes – Main cells that help in fighting infections
Granulocytes – These are W.B.C with granules which destroy microbes
Monocytes – These are related to granulocytes and also help the body fight against microbes
Red blood cells (R.B.C):
They are the ones that carry oxygen to all the tissues of the body.
Platelets:
They are very important in forming clots which prevents the blood vessels from bleeding.

How can cancer spread without lymph node involvement?
My aunts became clear lymph nodes, but found injuries to his liver has been diagnosed with breast cancer.They are doing a liver biopsy.We have no idea at this time if anything Iam ro cancer nothing.But praying for how can spead cancer without lymph node involvement? What is the possibility that this is just nothing? They did Blood tests came back as non-vascular
I have curiosity about what we mean by "did blood tests came back as non-vascular." The truth is that all tumors have a vasculature or may not survive. feed the tumors in the same oxygen and nutrients to the rest of your body is fed by, among others. As a result, cancer cells can enter the bloodstream and travel throughout the body, coming to rest in other places. The liver is a prime target for these malignant cells, since it acts as a filter for blood. The lymphatic system definitely plays a role, but not always positive nodes metastases precede distance.
