**Leukaemia** -Group of **blood cancers** -Consists on the **multiplication of abnormal cells in the blood**. -**Originated in the bone marrow**, inside the bones, where blood cells are created. -Levels of **functional cells** **decrease**. - **Symptoms:** bruising, bone pain, fatigue, increased risk of infection. -**Cause** of getting this disease: **unknown**, but **environmental** and **genetic factors** play a role. -People with a **family history** of leukaemia are at **higher risk.** - **4 main types of leukaemia***: (photo)* **-**ALL (acute lymphocytic leukaemia) -AML (acute myeloid leukaemia) -CLL (chronic lymphocytic leukaemia) -CML (chronic myeloid leukaemia) [Can be classified by: ] -**Development and duration:** acute or chronic. -**Cell involved:** lymphocytic *(lymphocytes)* or myeloid *(myeloid cells).* - **Treatments:** -**Bone marrow transplant.** **-Engineering immune cells** *(to fight the abnormal cells).* **-Radiation therapy.** - **Healthy habits to prevent infection** **Aneurysm** -Abnormal **bulging or balooning** of a **blood vessel wall**, as a result of a **weak spot** on it. \- **Causes:** It may be hereditary or caused by an acquired disease. -It can **burst**, causing **internal bleeding**, often leading to **death**. - **Symptoms:** usually they **don't cause symptoms**, so that you **can't notice**, even if it is **large**. - **Treatments:** - **Healthy habits to prevent infection**
