Lymphoma is a type of cancer that affects the lymphatic system and lymph nodes, which are crucial for the circulatory and immune systems. The disease is usually characterized by the existence of swollen lymph nodes, particularly in the regions of the neck and armpits. Night sweats, chills or fevers, unexpected weight loss, loss of appetite, lack of energy or tiredness, itching or rash, coughing, difficulties in breathing, enlarged tonsils, and headaches are other common signs of the disease.
There are different types of lymphomas, which determine the treatment and survival of patients. The past decades observed an increase in survival associated with lymphoma, which is considered the fastest growing and one the most common cancer types in the US. Survival has increased particularly in cases of early detection. Despite this fact, it is worth noting that the rates are conditioned by the time frame, which means that the statistics include a determined period and do not consider deaths after that period.
Lymphoma’s Incidence and Mortality
Currently, almost 93% of the patients suffering from regionally contained disease survive five years following the diagnosis, according to the National Cancer Institute, which may be explained by more accurate methods of diagnosis and cutting edge discoveries in the field. There are about 65.500 new lymphoma diagnoses annually in the US alone. From the total, about 20.000 people die due to the disease. The average age of diagnosis is 66 years old and the probability of suffering from the disease raises proportionally with age. The probability is also higher among men than women, while the average death age is 75.
Lymphoma’s Survival Rate by Disease Stage
The Surveillance Epidemiology and End Results (SEER) of the National Cancer Institute reveals the five year relative survival tendency of patients who suffer from lymphoma. Early-stage (I) with localized disease has a 81.1% survival rate, while early-stage (I, II) with regional disease has a 70.5% survival rate, and later-stage (III, IV), metastasized disease is 58.5%. The increase in survival rate is considered a success of cancer research. In addition to timing, the survival rate of lymphoma patients is also conditioned by the type of lymphoma in question and treatment chosen.
