Brain Tumors Caused by Depo Provera Birth Control


Brain Tumors Caused by Depo Provera Birth Control sue liable incident compensation lawyer attorney
Steven Ross

Reviewed by a STAFF ATTORNEY

A study has linked Pfizer’s Depo-Provera (or Depo Shot) with a significant risk of developing tumors, specifically, meningiomas. The study was conducted by the French National Agency for Medicines and Health Products Safety and the French National Health Insurance. They analyzed data from 100,000 women and found that the women who used the birth control shot for an extended length of time had a 5.6x higher risk of developing meningioma tumors when compared to women who did not use the depo shot.

Although meningiomas are often benign, the location in which they appear (usually on or around the brain) makes these tumors very dangerous, as they can lead to many complications and require surgery or other aggressive forms of treatment to address. If you or a loved ne developed these tumors after the use of the depo shot as a form of birth control, it is important that you seek the guidance of a lawyer to explore the possibility of filing a depo shot meningioma lawsuit.

In the following sections, we will review meningioma tumors, including the types of tumors, the different symptoms/complications associated with the tumors, where these tumors appear, treatment options, and more.

What are Meningioma Tumors?

Meningiomas are a type of tumors that form in the meninges; the meninges are the protective membranes that cover the brain and spinal cord. Typically, these tumors are benign. However, because of where they appear, they can be dangerous. These tumors can result in a number of complications.

Where Do Meningiomas Form?

These tumors can potentially form and appear in/on the following:

  • On the surface of the brain
  • Between the two sides of the brain
  • Within the chambers of the brain
  • In the bones at the base of the skull
  • In the bony ridge behind the eyes
  • On the skull base behind the eyes
  • On the nerves connecting the brain to the nose
  • On the underside of the brain near the cerebellum
  • Near the pituitary gland
  • Near the optic nerve
  • In or around the eye sockets
  • Where the brain connects with the brainstem
  • In the spine or against the spinal cord
What are the Complications or Symptoms Associated with Meningiomas?

Meningiomas could result in many different symptoms/complications based on where the tumor is located. Examples of the complications and symptoms that affected women could experience include the following:

  • Compression of the brainstem, which can affect all vital functions (a tumor compressing the brainstem is considered life-threatening)
  • Compression of the auditory nerve (hearing loss, hearing problems, balance problems, etc.)
  • Hydrocephalus caused by increased intracranial pressure (headaches, vision problems, nausea, etc.)
  • Problems with neurological functions (sensory loss, motor weakness, difficulties with language, cognitive impairment, etc.)
  • Seizures

The complications from meningiomas could prevent women from being able to complete their normal, everyday tasks. For some, complications from meningiomas could strip away their independence.

What are the Types of Meningioma Tumors?

As previously stated, meningiomas form in the protective membranes that cover the brain and the spinal cord. There are three different types of meningiomas, which are described below:

  • Grade I Meningiomas – a noncancerous, slow-growing tumor. This is the most common type of meningioma, accounting for up to 85% of all cases.
  • Grade II Meningiomas – atypical tumors that have a higher change of recurring after they have been treated/removed.
  • Grade III Meningiomas – fast-growing tumors with the highest recurrence rate. These tumors are often malignant.
Do Meningioma Tumors Require Surgery?

Yes, meningiomas usually must be surgically removed. Like all surgeries, surgeries to address meningiomas come with risks, including infections, blood loss, leaking fluids, and more. In most cases, symptoms/complications caused by the tumor are immediately relieved (like symptoms caused by the tumor pressing up against a nerve).

Some tumors that are in difficult areas to reach with surgery may require radiation therapy. The same applies to cancerous tumors. Some patients may need both surgery and radiation therapy. Of course, radiation therapy and other aggressive non-surgical options come with added risks.

In addition to the physical and psychological harm resulting from the actual tumor, women suffering from meningiomas may experience additional physical and psychological damages associated with going through treatment.

Can I File a Lawsuit for Meningiomas Caused by the Depo Shot?

Yes, you could have the right to file a lawsuit. You could file a lawsuit or participate in a class action lawsuit against Pfizer, the manufacturer of the Depo-Provera shot. Pfizer could be liable for all harm resulting from the use of their birth control shot based on the failure to identify the risk of meningioma and properly warn the public about the risk present. This means that Pfizer could be sued for harm resulting from their birth control shot.

If you or a loved one suffered a brain tumor or meningioma due to the use of the birth control shot, it is important that you seek legal assistance as soon as possible.
