Blood malignancies or interfere with both the production and functioning of blood cells. Although all can impair the immune system, some of them may significantly weaken the immune system. There are four major subtypes of blood cancer, including leukemia, lymphoma, multiple myeloma, and myelodysplastic syndromes, and all of them have distinct traits, causes, symptoms, and methods of treatment. Each is described below in detail.
1. Leukemia
Leukemia is a blood cancer of the tissue that produces blood. Mostly, it is the bone marrow. The disease causes more than the normal amounts of abnormal white blood cells, which occur in place of the white blood cells and cells that produce blood. This later results in the appearance of many other medical conditions.
Types of Leukemia:
Leukemia has two forms. There are two main types according to the speed at which the disease takes its toll. In this classification, the disease progresses slowly or gradually. In this classification, the intervals at which deterioration takes place occur slowly. Another class is that which is classified depending on the type of specific blood cell involved.
Acute Leukemia: Acute leukemia is a very aggressive type of disease and needs to be treated right away. They can be broadly divided into two subtypes: ALL and AML.
Chronic Leukemia: Chronic leukemia advances at a very rapid speed and can be treated for years. CLL and CML are the two major subdivisions of it.
Symptoms
The symptoms of leukemia tend to vary from one case to another, but common ones are as outlined below:
- One develops this weak and tired feeling
- Infections keep on recurring
- Bruises or bleeding are exposed
- Weight has been lost
- There are swollen lymph nodes or the spleen
Treatment
Treatment of leukemia generally covers the following:
Chemotherapy: This is the main treatment interference to treat cancerous cells.
Radiation Therapy: It may sometimes be provided directly from the radiation center to target cancerous cells in specific areas.
Stem Cell Transplant: It may sometimes require the reconstitution of healthy blood cells through the transplantation of stem cells.
Targeted Therapy: Targeted drugs in the form of drugs that will kill cancerous cells.
2. Lymphoma
This is a cancerous tissue growing within the lymphatic system, which is one of the organ components of the body’s immune system. It has been linked with abnormal growths of lymphocytes, which is one of the white blood cells.
Types of Lymphoma
Lymphomas have been categorized broadly into two;
Hodgkin Lymphoma: It is the most curable category of lymphoma in comparison to non-Hodgkin lymphoma. The characteristic of this category is the presence of Reed-Sternberg cells.
Non-Hodgkin Lymphoma (NHL): This is the general term for the general categories and types of . Some cases are aggressive, while others are rather slow in their occurrence.
Common Symptoms
- Besides lymphoma symptoms, it is not odd to experience:
- Enlarged lymph nodes in the neck, underarm, or groin area
- Fever
- Night sweats
- Weight loss
- Fatigue
- Itching skin
Treatment
The treatments for lymphomas are determined by the type and may include:
Chemotherapy: It is widely utilized both in Hodgkin and non-Hodgkin lymphoma treatment
Radiation Therapy: In most patients who have localized disease, it is often used in combination with chemotherapy.
Immunotherapy: Medications that can make the immune system identify cancerous cells and kill them
Stem: Cell Transplant In an advanced stage.
3. Multiple Myeloma
Multiple myeloma is a cancer of plasma cells. Plasma cells are white blood cells that produce antibodies. In multiple myeloma, there is the abnormal proliferation of plasma cells in the bone marrow, which produces ineffective antibodies, thereby causing many complications.
Symptoms
Multiple myeloma may have the following symptoms:
- Back and rib cage pain
- Pain
- Recurring infections
- Anemia
- The disorder of High calcium levels causes problems with the kidneys.
- Weakness and numbness
Diagnosis
Diagnosis is typically established:
- Blood tests to detect abnormal proteins.
- Bone marrow biopsy-to determine the percentage of myeloma cells
- Imaging studies, such as X-rays or MRIs, to determine the bone density
Therapy
Therapy for multiple myeloma may include:
Chemotherapy: Generally given first.
Targeted Therapy: Proteasome inhibitors or immunomodulatory drugs, among others.
Stem Cell Transplant: Generally given to certain patients after initial therapy.
Bisphosphonates: To prevent loss of bone and fractures.
4. Myelodysplastic Syndromes (MDS)
Myelodysplastic syndromes are a group of conditions in which poorly formed, or otherwise defective, blood cells are present. MDS is sometimes called “pre-leukemia” because the disease can become acute leukemia.
Causes
- MDS is caused by several different factors. These include;
- Anti-cancer chemotherapy or radiation.
- Exposure to certain chemicals such as benzene.
- Genetic predispositions
Symptoms
- General symptoms of MDS include
- Tiredness and weakness
- High infection risks due to low white blood cells
- Bleeding or bruising easily
- Shortness of breath by anemic patients
Treatment
For MDS, the following can be used;
Supportive Therapy: Blood transfusions, other than growth factors that induce blood cell counts.
Chemotherapy: In some patients, to prevent symptom development and sometimes to avoid leukemia itself.
Stem Cell Transplantation: Till now, these are the only source of hope for many patients, mainly young patients.
Clinical Trails: There are still various modes of treatment under research.
Conclusion
Blood cancers can be termed as an amalgam of the various conditions affecting blood, bone marrow, and the lymphatic system. There are different forms, namely, various leukemias, lymphomas, multiple myelomas, and myelodysplastic syndromes. Even though they have different features, one thing in common is an abnormal function of blood cells. It has completely revolutionized the prognosis for so many patients who get diagnosed with these cancers through early diagnosis as well as advancements in treatment. Ongoing research is always discovering better therapeutic strategies and possible cures for those patients diagnosed with blood cancers. This may embolden the patients and family members to search for appropriate care and support.
