Yes, primary nodules don't have germinal centers(active B cells) while secondary nodules do.
Mineral nodules on the ocean floor are considered a nonrenewable resource because their formation takes millions of years through geological processes, making them extremely slow to replenish. Once harvested, the extraction of these nodules can deplete the resource significantly, as they do not regenerate at a rate that can keep up with human consumption. Furthermore, the environmental impact of mining these nodules can lead to irreversible damage to marine ecosystems, further emphasizing their nonrenewable nature.
Thyroid nodules are relatively common, and many are benign. A 2.7 cm thyroid nodule is considered large and may require further evaluation, such as an ultrasound or biopsy, to determine its nature. While some nodules can be normal and non-cancerous, any significant size increase or suspicious features should be assessed by a healthcare professional. Regular monitoring is often recommended for nodules of this size.
No. Spleen nodules cannot grow in human or any other lungs. Spleen nodules grow on the spleen. There are nodules that do grow in the lungs, however.
A thyroid nodule is a lump in or on the thyroid gland. Any time a lump is discovered in thyroid tissue, the possibility for cancer needs to be considered. Fortunately, the vast majority of thyroid nodules tend to be benign.
The nodules likely refer to thyroid nodules. The process within these nodules involves the formation of abnormal growths or lumps on the thyroid gland. These nodules can be benign or malignant and may affect thyroid function. Further evaluation, such as biopsy or imaging, may be needed to determine the nature of the nodules.
Nodules usually only require voice therapy; less than 5% of nodules require surgery
According to the American Association of Clinical Endocrinologists, a thyroid nodule is a lump in or on the thyroid gland. Any time a lump is discovered in thyroid tissue, the possibility for cancer needs to be considered. Fortunately, the vast majority of thyroid nodules tend to be benign. The AACE says nodules can be caused by a simple overgrowth of normal thyroid tissue, fluid-filled cysts, inflammation, or a tumor.
Vocal nodules typically do not require a biopsy as they are benign lesions resulting from vocal strain or misuse. Diagnosis is usually made through a laryngeal examination and the patient's history. However, if there is suspicion of malignancy or if the nodules do not respond to conservative treatment, a biopsy may be considered to rule out other conditions. Always consult with a laryngologist for an appropriate evaluation and management plan.
yes,there are root nodules

Nodules are hard to mine because they are found in very deep water
