Leukemia is tumor of blood cells and blood cells precursors not only lymphocytes it can be anything for example in CML you have proliferation of all cell lineages.
Dx, Bone Marrow biopsy

Lymphoma is a tumor of lymphoid tissue mainly sub-classified into Hodgkin's and non-Hodgkin's
Dx, Lymph node biopsy
Remember it's these lymphoid tissues were lymphocytes and precursors get matured.

Perhaps u r confused because of the fact that sometimes blood tumors may have elements of both for example T-Cell ALL closely resembles Lymphocytic lymphoma with thymic shadows.

  • Leukaemias are a group of cancers of the blood-forming cells. They start in the bone marrow. The abnormal cells spread from there into the bloodstream and to other parts of the body. leukemia is devided to Lymphoid and myeloid.
  • Lymphomas are cancers of the lymphatic system. The lymphatic system is a complex network. Lymph nodes are found in the neck, armpits, groin, chest, abdomen and pelvis.
so the main way to diagnose leukemia is Bone marro biopsy, while we diagnose lymphomas with biopsies of lymh nodes, thymus, spleen,...

think like this...
leukemia is in the blood
lymphoma is in the lymph nodes

leukemia you do you do blood exams, bone marrow exams
lymphoma you must do a biopsy

of course I am simplifying things...
