An adenoma is a benign tumor that develops in the glands and epithelial tissues. Although it is not cancerous, it can cause various disorders depending on its location. Adenomas can affect several organs, including the thyroid, prostate, adrenal glands, liver, and pituitary gland.
The main causes of adenoma formation include hormonal factors, genetic predisposition, an unbalanced diet, and exposure to certain environmental toxins. For example, a hepatic adenoma is often associated with prolonged use of oral contraceptives or anabolic steroids, while a prostate adenoma can be influenced by aging and hormonal imbalance.
The symptoms of an adenoma vary depending on the affected organ. Some remain asymptomatic and are discovered incidentally during a medical examination, while others cause more or less disabling functional disorders.
A pituitary adenoma can lead to excessive hormone production, causing hormonal imbalances such as acromegaly, hyperprolactinemia, or Cushing’s disease.
A hepatic adenoma, often asymptomatic, may cause abdominal pain and pose a risk of hemorrhagic rupture.
A prostate adenoma results in urinary disorders such as dysuria, frequent urination (pollakiuria), or a feeling of incomplete bladder emptying.
An adrenal adenoma can be hormone-secreting, leading to high blood pressure, abnormal weight gain, and metabolic disorders.
A thyroid adenoma can produce an excess of thyroid hormones, leading to hyperthyroidism, which may cause palpitations, weight loss, and increased nervousness.
The management of an adenoma depends on its type, size, and symptoms. In most cases, regular medical monitoring is recommended to track its progression. However, certain treatments may be considered.
Medication treatment is often preferred for hormonal adenomas to regulate hormone production and limit symptoms.
Surgery is recommended when the adenoma is large, exerts pressure on nearby organs, or presents a risk of complications such as hemorrhage or malignant transformation.
Radiotherapy may be considered for pituitary adenomas or other types that are difficult to treat with surgery alone.
Lifestyle changes are also advised. A balanced diet, regular hormonal monitoring, and stopping the use of steroids or certain hormonal medications can help limit the occurrence or progression of certain adenomas.
An adenoma is a benign tumor, meaning it generally does not turn into cancer. However, in rare cases, some adenomas can evolve into a malignant form, such as an adenocarcinoma. Regular medical monitoring is therefore essential.
The diagnosis of an adenoma relies on various medical tests: ultrasound, MRI, CT scan, or even a biopsy if necessary. Some adenomas are discovered incidentally, while others are suspected due to persistent symptoms.
Some small adenomas may shrink or disappear spontaneously, especially hepatic adenomas after stopping oral contraceptives. However, most require medical follow-up to prevent any complications.
The main risk factors include aging, hormonal imbalances, long-term use of hormonal medications, heredity, and exposure to toxic substances.
Reducing risk is possible by adopting a healthy lifestyle, limiting the use of unnecessary hormonal medications, monitoring hormonal balance, and undergoing regular medical check-ups, especially in cases of family history.
Benign prostatic hyperplasia is an abnormal development of the prostate gland. Symptoms include obstruction of bladder evacuation (weak urine stream). The symptoms then gradually progress to incontinence. We will explain the principle of hypertrophy before looking at the symptoms and possible complications. What is benign prostatic hyperplasia? In some men, as they get older, the … Read more

Among the problems it causes are urinary and erectile problems. It’s true that this situation is frightening, but it needn’t be taken for granted. Rest assured, … Read more
The thyroid is an endocrine (or hormonal) gland, located against the esophagus and which is schematically shaped like a bow tie. It is essentially made up of vesicles with walls made up of a single layer of cells, and which contain the colloid, mainly made up of thyroglobulin. The two hormones secreted by the thyroid … Read more
